grib_compare

-DESCRIPTION

-Compare grib messages contained in two files. If some differences are found it fails returning an error code. Floating point values are compared exactly by default, different tolerance can be defined see -P -A -R. Default behaviour: absolute error=0, bit-by-bit compare, same order in files.

-USAGE

-grib_compare [options] grib_file grib_file

-OPTIONS

--r
- Compare files in which the messages are not in the same order. This option is time expensive.
-
- -b key,key,...
- All the keys in this list are skipped in the comparison. Bit-by-bit compare on.
-
- -e
- edition independent compare. It is used to compare grib edition 1 and 2.
-
- -c key[:l/d/s/n],key[:l/d/s/n],...
- Only the listed keys or namespaces (:n) are compared. The optional letter after the colon is used to force the type in the comparison: l->integer, d->float, s->string, n->namespace. See -a option. Incompatible with -H option.
-
- -a
- -c option modifier. The keys listed with the option -c will be added to the list of keys compared without -c.
-
- -H
- Compare only message headers. Bit-by-bit compare on. Incompatible with -c option.
-
- -R key1=relative_error1,key2=relative_error2,...
- Compare floating point values using the relative error as tolerance. key1=relative_error will compare key1 using relative_error1. all=relative_error will compare all the floating point keys using relative_error. Default all=0.
-
- -A absolute error
- Compare floating point values using the absolute error as tolerance. Default is absolute error=0
-
- -P
- Compare data values using the packing error as tolerance.
-
- -T factor
- Compare data values using factor multipied by the tolerance specified in options -P -R -A.
-
- -w key[:{s/d/l}]{=/!=}value,key[:{s/d/l}]{=/!=}value,...
- Where clause. Grib messages are processed only if they match all the key/value constraints. A valid constraint is of type key=value or key!=value. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be specified. Default type is string.
-
- -f
- Force. Force the execution not to fail on error.
-
- -V
- Version.
-
- -7
- Does not fail when the message has wrong length
-
- -v
- Verbose.
-
-

-grib_compare examples

-
    -
  1. The default behaviour for grib_compare without any option is to perform a bit by bit comparison of the two messages. If the messages are found to be bitwise different then grib_compare switches to a "key based" mode to find out which coded keys are different. To see how grib_compare works we first set the shortName=2d (2 metre dew point temperature) in the file regular_latlon_surface.grib1
    - 
    ->grib_set -s shortName=2d regular_latlon_surface.grib1 2d.grib1
-
    Then we can compare the two fields with grib_compare.
    - 
    ->grib_compare regular_latlon_surface.grib1 2d.grib1
-
--- GRIB #1 -- shortName=2t paramId=167 stepRange=0 levelType=sfc level=0 packingType=grid_simple gridType=regular_ll --
-long [indicatorOfParameter]: [167] != [168]
-
    In the output we see that the only "coded" key with different values in the two messages is indicatorOfParameter which is the relevant key for the parameter information. The comparison can be forced to be successful listing the keys with different values in the -b option. 
    ->grib_compare -b indicatorOfParameter regular_latlon_surface.grib1 2d.grib1
-

    -
    -
  2. Two grib messages can be very different because they have different edition, but they can contain the same identical information in the header and the same data. To see how grib_compare can help in comparing messages with different edition we do 
    ->grib_set edition=2 reduced_gaussian_model_level.grib1 reduced_gaussian_model_level.grib2
-
    Then we compare the two fields with grib_compare.
    - 
    ->grib_compare reduced_gaussian_model_level.grib1 reduced_gaussian_model_level.grib2
-
--- GRIB #1 -- shortName=t paramId=130 stepRange=0 levelType=ml level=1 packingType=grid_simple gridType=reduced_gg --

-[padding_grid4_1] not found in 2nd field
-long [section4Length]: [9948] != [770]
-[dataFlag] not found in 2nd field
-
    It is clear that the two messages are coded in a very different way. If we now add the -e option, the tool will compare only the higher level information common between the two messages. 
    ->grib_compare -e reduced_gaussian_model_level.grib1 reduced_gaussian_model_level.grib2
-
    The comparison is successful because the two messages contain the same information coded in two different ways. We can display the list of keys used by grib_compare adding the option -v (verbose). 
    ->grib_compare -ve reduced_gaussian_model_level.grib1 reduced_gaussian_model_level.grib2

-1 of 1 grib messages in reduced_gaussian_model_level.grib2
-
-1 of 1 total grib messages in 1 files
-
    For each key the type used in the comparison is reported and for the floating point keys also the tolerance used is printed.
    -
    -
  3. Some options are provided to compare only a set of keys in the messages. The option -H is used to compare only the headers coded in the message, it doesn't compare the data values. The option "-c key1:[l/d/s/n],key2:[l/d/s/n],... " can be used to compare a set of keys or namespaces. The letter after the colon is optional and it is used to force the type used in the comparison which is otherwise assumed to be the native type of the key. The possible types are:
      -
    • :l -> integer (C type long)
    • :d -> floating point (C type double)
    • :s -> string
    • :n -> namespace.
    -When the type "n" is used all the set of keys belonging to the specified namespace are compared assuming their own native type. To illustrate how these options work we change the values coded in a message using grib_filter with the following rules file (see grib_filter). 
    -set bitsPerValue=10;
-set values={1,2.5,3,4,5,6,70};
-write "first.grib1";
-set values={1,2.5,5,4,5,6,70};
-write "second.grib1";
-
    We first compare the two files using the -H option (only headers are compared). 
    ->grib_compare -H first.grib1 second.grib1
-
    The comparison is successful because the data are not compared. To compare only the data we have to compare the "data namespace". 
    ->grib_compare -c data:n first.grib1 second.grib1
-
--- GRIB #1 -- shortName=t paramId=130 stepRange=0 levelType=ml level=1 packingType=grid_simple gridType=reduced_gg --
-double [packedValues]: 1 out of 7 different,  max absolute diff. = 2, relative diff. = 0.4
-	max diff. element 2: 3.00000000000000000000e+00 5.00000000000000000000e+00
-	tolerance=0 packingError: [0.04] [0.04]
-	values max= [70.04]  [70.04]         min= [1] [1]
-
    The comparison is showing that one of seven values is different in a comparison with the (default) absolute tolerance=0. We can change the tolerance with the -A option: 
    ->grib_compare -A 2 -c data:n first.grib1 second.grib1
-
    and we see that the comparison is successful if the absolute tolerance is set to 2. We can also set the relative tolerance for each key with the option -R: 
    ->grib_compare -R packedValues=0.4 -c data:n first.grib1 second.grib1
-
    and we get again a successful comparison because the relative tolerance is bigger than the relative absolute difference of two corresponding values. Another possible choice for the tolerance is to be equal to the packingError, which is the error due to the packing algorithm. If we change the decimalPrecision of a packed field we introduce a packing error sometimes bigger than the original packing error. 
    ->grib_set -s changeDecimalPrecision=0 first.grib1 third.grib1
-
    and we compare the two fields using the -P option (tolerance=packingError). 
    ->grib_compare -P -c data:n first.grib1 third.grib1
-
    the comparison is successful because their difference is within the biggest of the two packing error. With the option -P the comparison is failing only if the original data coded are different, not if the packing precision is changed. If we try again to compare the fields without the -P option: 
    ->grib_compare -c data:n first.grib1 third.grib1
-
--- GRIB #1 -- shortName=t paramId=130 stepRange=0 levelType=ml level=1 packingType=grid_simple gridType=reduced_gg --
-double [packedValues]: 4 out of 7 different,  max absolute diff. = 0.48, relative diff. = 0.16
-	max diff. element 1: 2.52000000000000001776e+00 3.00000000000000000000e+00
-	tolerance=0 packingError: [0.04] [0.5]
-	values max= [70.04]  [70]         min= [1] [1]
-
    we see that some values are different and that the maximum absolute differenc is close to the biggest packing error (max diff=0.48 packingError=0.5). The packing error was chosen to be 0.5 by setting decimalPrecision to 0 which means that we don't need to preserve any decimal figure.
    -
    -
  4. When we already know that the fields are not numerically identical, but have similar statistical characteristics we can compare their statistics namespaces: 
    ->grib_compare -c statistics:n first.grib1 third.grib1
-
--- GRIB #1 -- shortName=t paramId=130 stepRange=0 levelType=ml level=1 packingType=grid_simple gridType=reduced_gg --
-double [max]: [7.00400000000000062528e+01] != [7.00000000000000000000e+01]
-	absolute diff. = 0.04, relative diff. = 0.000571102
-	tolerance=0
-double [avg]: [1.30914285714285707485e+01] != [1.31428571428571423496e+01]
-	absolute diff. = 0.0514286, relative diff. = 0.00391304
-	tolerance=0
-double [sd]: [2.32994686809877009637e+01] != [2.32589679873534969090e+01]
-	absolute diff. = 0.0405007, relative diff. = 0.00173827
-	tolerance=0
-double [skew]: [-1.41592875700515623549e+01] != [-1.41669971380493855406e+01]
-	absolute diff. = 0.00770957, relative diff. = 0.000544192
-	tolerance=0
-double [kurt]: [7.32364710785659567271e-01] != [7.32723797489455375143e-01]
-	absolute diff. = 0.000359087, relative diff. = 0.000490071
-	tolerance=0
-
    and we see that maximum, minimum, average, standard deviation, skewness and kurtosis are compared. While the values are different by 0.48 the statistics comparison shows that the difference in the statistical values is never bigger than 0.052 
    ->grib_compare -A 0.052 -c statistics:n first.grib1 third.grib1
-
    The statistics namespace is available also for spherical harmonics data and provides information about the field in the geographic space computing them in the spectral space for performance reasons.
    -
    -
  5. When a file contains several fields and some keys are different, it is useful to have a summary report of the keys found different in the messages. This can be obtained with the option -f. We change few keys in a file: 
    ->grib_set -w typeOfLevel=surface -s step=48 tigge_pf_ecmwf.grib2 out.grib2
-
    and comparing with the -f option: 
    ->grib_compare -f tigge_pf_ecmwf.grib2 out.grib2
-
--- GRIB #9 -- shortName=skt paramId=235 stepRange=96 levelType=sfc level=0 packingType=grid_simple gridType=regular_ll --

-
-
    we get a list of all the different messages in the files and a summary report of the different keys.
    -

  6. We can change the order of the messages in a file using grib_copy with the -B option: 
    ->grib_copy -B typeOfLevel tigge_pf_ecmwf.grib2 out.grib2

    If we now compare the two files: 
    ->grib_compare -f tigge_pf_ecmwf.grib2 out.grib2

    the comparison is failing because of the different order of the messages. We can use the -r option to compare the files assuming that the messages are not in the same order: 
    ->grib_compare -r tigge_pf_ecmwf.grib2 out.grib2
-
    and we have a successful comparison because for each message in the first file an identical message is found in the second file. This option should be used carefully as it is very time expensive.

grib_copy

-DESCRIPTION

-Copies the content of grib files printing values of some keys.

-USAGE

-grib_copy [options] grib_file grib_file ... output_grib_file

-OPTIONS

--f
- Force. Force the execution not to fail on error.
-
- -r
- Repack data. Sometimes after setting some keys involving properties of the packing algorithm a repacking of data is needed. This repacking is performed setting this -r option.
-
- -p key[:{s/d/l}],key[:{s/d/l}],...
- Declaration of keys to print. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be requested. Default type is string.
-
- -P key[:{s/d/l}],key[:{s/d/l}],...
- As -p adding the declared keys to the default list.
-
- -w key[:{s/d/l}]=value,key[:{s/d/l}]=value,...
- Where clause. Only grib messages matching the key/value constraints are copied to the output_grib_file. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be defined. Default type is string.

-grib_filter examples

-
    -
  1. The rules accepted by grib_filter are different from the grib_convert rules due to the kind of work grib_filter it is supposed to do.
    - The main difference between grib_filter and grib_convert is that the convert is a 1 field in input 1 field in output tool, while the filter is a 1 field in input as many field you need in output. At this aim the filter syntax allows a write in the form: write "filename". So that it is possible repeating as many write you need or using a parametrised write to send the output to many files.
    - The grib_filter processes sequentially all the grib messages contained in the input file and it applies the rules to each one.
    - Since the filename used in the write statement can contain some key values, taken from the grib processed when applying the "write rule", several files are produced in output containing fields with the same value of the keys used in the file name.
    - Indeed if we write a rules_file containing the only statement:
    -
    - 
    -write "../data/split/[centre]_[date]_[dataType]_[levelType].grib[editionNumber]";
-

    - Applying this rules_file to the ../data/tigge_pf_ecmwf.grib2 grib file we obtain several files in the ../data/split directory containting fields splitted according their keys values
    - 
    ->grib_filter rules_file ../data/tigge_pf_ecmwf.grib2
->ls ../data/split
-ecmf_20060619_pf_sfc.grib2
-ecmf_20060630_pf_sfc.grib2
-ecmf_20070122_pf_pl.grib2
-ecmf_20070122_pf_pt.grib2
-ecmf_20070122_pf_pv.grib2
-ecmf_20070122_pf_sfc.grib2
-

    -
  2. The key values in the file name can also be obtained in a different format by indicating explicitly the type required after a colon.
      -
    • :l for long
    • :d for double
    • :s for string
    -The following statement works in a slightly different way from the previous example, including in the output file name the long values for centre and dataType.
    - 
    -write "../data/split/[centre:l]_[date]_[dataType:l]_[levelType].grib[editionNumber]";
-

    - Running the same command again we obtain a different list of files.
    - 
    ->grib_filter rules_file ../data/tigge_pf_ecmwf.grib2
->ls ../data/split
-98_20060619_4_sfc.grib2
-98_20060630_4_sfc.grib2
-98_20070122_4_pl.grib2
-98_20070122_4_pt.grib2
-98_20070122_4_pv.grib2
-98_20070122_4_sfc.grib2
-

    -
  3. Other statements are allowed in the grib_filter syntax:
      -
    • if ( condition ) { statement;}
      - The condition can be made using ==,!= and joining single block conditions with || and &&
      - The statement can be any valid statement also another nested condition
      -
    • set keyname = keyvalue;
    • print "string to print also with key values like in the file name"
    • transient keyname1 = keyname2;
    • comments beginning with #
    -A complex example of grib_filter rules is the following to change temperature in a grib edition 1 file. 
    -# Temperature
-if ( level == 850 && indicatorOfParameter == 11 ) {
-    print "found indicatorOfParameter=[indicatorOfParameter] level=[level] date=[date]";
-    transient oldtype = type ;
-    set identificationOfOriginatingGeneratingSubCentre=98;
-    set gribTablesVersionNo = 128;
-    set indicatorOfParameter = 130;
-    set localDefinitionNumber=1;
-    set marsClass="od";
-    set marsStream="kwbc";
-    # Negatively/Positively Perturbed Forecast
-    if ( oldtype == 2 || oldtype == 3 ) {
-      set marsType="pf";
-      set experimentVersionNumber="4001";
-    }
-    # Control Forecast
-    if ( oldtype == 1 ) {
-      set marsType="cf";
-      set experimentVersionNumber="0001";
-    }
-    set numberOfForecastsInEnsemble=11;
-    write;
-    print "indicatorOfParameter=[indicatorOfParameter] level=[level] date=[date]";
-    print;

grib_set

-DESCRIPTION

-Sets key/value pairs in the input grib file and writes each message to the output_grib_file. It fails when an error occurs (e.g. key not found).

-USAGE

-grib_set [options] grib_file grib_file ... output_grib_file

-OPTIONS

--s key[:{s/d/l}]=value,key[:{s/d/l}]=value,...
- Key/values to set. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be defined. By default the native type is set.
-
- -r
- Repack data. Sometimes after setting some keys involving properties of the packing algorithm a repacking of data is needed. This repacking is performed setting this -r option.
-
- -d value
- Set all the data values to "value".
-
- -p key[:{s/d/l}],key[:{s/d/l}],...
- Declaration of keys to print. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be requested. Default type is string.
-
- -P key[:{s/d/l}],key[:{s/d/l}],...
- As -p adding the declared keys to the default list.
-
- -w key[:{s/d/l}]=value,key[:{s/d/l}]=value,...
- Where clause. Set is only executed for grib messages matching all the key/value constraints. If a grib message does not match the constraints it is copied unchanged to the output_grib_file. This behaviour can be changed setting the option -S. For each key a string (key:s) or a double (key:d) or a long (key:l) type can be defined. Default type is string.
-
- -7
- Does not fail when the message has wrong length
-
- -S
- Strict. Only grib messages matching all the constraints are copied to the output file
-
- -V
- Version.
-
- -M
- Multi-grib support off. Turn off support for multiple fields in single grib message
-
- -g
- Copy GTS header.
-
- -G
- GRIBEX compatibility mode.
-
- -f
- Force. Force the execution not to fail on error.
-
- -v
- Verbose.
-
-

-grib_set examples

-
    -
  1. To set productDefinitionTemplateNumber=2 only for the fields with productDefinitionTemplateNumber=11
    - 
    ->grib_set -s productDefinitionTemplateNumber=2 -w productDefinitionTemplateNumber=11 ../data/tigge_pf_ecmwf.grib2 out.grib2
-

    -
  2. To set productDefinitionTemplateNumber=2 only for the fields for which productDefinitionTemplateNumber is not equal to 11
    - 
    ->grib_set -s productDefinitionTemplateNumber=2 -w productDefinitionTemplateNumber!=11 tigge_pf_ecmwf.grib2 out.grib2
-

    -
  3. When a key is not used all the bits of its value should be set to 1 to indicate that it is missing. Since the length (number of octet) is different from a key to another, the value that we have to code for missing keys is not unique. To give an easy way to set a key to missing a string "missing" or "MISSING" is accepted by grib_set as follows:
    - 
    ->grib_set -s scaleFactorOfFirstFixedSurface=missing,scaledValueOfFirstFixedSurface=MISSING ../data/regular_latlon_surface.grib2 out.grib2
-

    - Since some values can not be set to missing you can get an error for those keys.
  4. To set scaleFactorOfSecondFixedSurface to missing only for the fields for which scaleFactorOfSecondFixedSurface is not missing:
    - 
    ->grib_set -s scaleFactorOfSecondFixedSurface=missing -w scaleFactorOfSecondFixedSurface!=missing tigge_pf_ecmwf.grib2 out.grib2
-

    -
  5. It's possible to produce a grib edition 2 file from a grib edition 1 just changing the edition number with grib_set. At this stage of development all the geography parameters, level and time information is correctly translated, for the product definition extra set calls must be done. To do this properly grib_convert is suggested.
    - 
    -grib_set -s editionNumber=2 ../data/reduced_gaussian_pressure_level.grib1
-

    -
  6. With grib edition 2 is possible to compress data using the jpeg algorithm. To change packing algorithm from grid_simple (simple packing) to grid_jpeg (jpeg2000 packing):
    - 
    ->grib_set -s packingType=grid_jpeg ../data/regular_gaussian_model_level.grib2 out.grib2
-

    -
  7. It's possible to ask grib_api to calculate the number of bits per value needed to pack a given field with a fixed number of decimal digits of precision. For example if we want to pack a temperature expressed in Kelvin with 1 digits of precision after the decimal point we can set changeDecimalPrecision=1
    - 
    ->grib_set -s changeDecimalPrecision=1 ../data/regular_latlon_surface.grib2 ../data/out.grib2
-rm -f ../data/out.grib2 | true
-./grib_set -s changeDecimalPrecision=1 ../data/regular_latlon_surface.grib2 ../data/out.grib2

Grib API keys

The GRIBEX routine used at ECMWF to encode and decode GRIB messages works on a number based table to retrive all the information from the message. This approach forces the user either to learn a code table or to use the documentation intensively. With grib_api a key name based access is provided so that all the information contained in the GRIB message is retrieved through alphanumeric names.
- All the key names are built from the official WMO documentation on the GRIB edition 1 and 2 coding standard removing the spaces in the key description and capitalizing the initials so that the caption:
- 
-identification of originating generating centre
-
is transformed into the key name
- 
-identificationOfOriginatingGeneratingCentre
-

- Some short names (aliases) are also provided, e.g. "centre" is an alias for identificationOfOriginatingGeneratingCentre. The names are always easily releated to the meaning of their value.
- A different set of keys is available for each message because the content is different. It is easy to find the keys available in a message by using the GRIB tools (grib_dump) or the library (keys_iterator.c).
-

-Coded and Computed keys

-There are two different types of keys: coded and computed.
- The coded keys are directly linked to octets of the GRIB message and their value is obtained by only decoding the octets. A list of all the coded keys in a message can be obtained using grib_dump without any option (use the -a option to obtain also their aliases).
- The computed keys are obtained by combining other keys (coded or computed) and when their value is set all the related keys are set in a cascade process.
- These keys provide a synthesis of the information contained in the GRIB message and are a safe way to set complex attributes such as the type of grid or the type of packing. They are also helpful in the interpretation of some octets such as the scanning mode whose bits are related to the way of scanning the grid. In this case the computed keys:
- 
-iScansNegatively
-jScansPositively
-jPointsAreConsecutive
-alternativeRowScanning (available only for edition 2)
-

- will provide access to single bits of the scanning mode octect hiding its structure from the user.
- The keys can also have some attributes as read only, which means that the key cannot be set (e.g. 7777 at the end of the message), or edition specific that is the attribute of all the keys having different values in the two editions (e.g. longitudeOfFirstGridPoint) or being present in one edition only (e.g. alternativeRowScanning).
- Moreover there are some computed keys that cannot be "get" and can be considered as functions acting on the grib in some way. These keys are always characterised by a predicate in their name (e.g. setDecimalPrecision).
- For the computed keys we provide the following preliminary documentation that will be extended soon. -

Grib tools

The following command line tools are provided to help users in all interactive and batch processing of grib data.
- Use of the tools is recommended whenever possible. They provide a ready and tested solution for many situations and their use will avoid the need to write new cod and thus speeding up your work.
- To make easier their use the tools are provided with a common set of options so that it's quick to apply the same options to different tools. We suggest to begin with grib_dump, grib_ls and grib_get to inspect the content of some files and then to learn about the other tools to change the content of the grib message (grib_set, grib_convert, grib_filter) or to copy some messages from a file (grib_copy) or to get a latitude/longitude/values list of data. A smart compare tool (grib_compare) is also provided to compare grib messages focusing on some keys or comparing data with a given precision.
