! FORTRAN 90 Implementation: bufr_read_temp
|
|
!
|
|
! Description: how to read levels from TEMP BUFR messages.
|
|
!
|
|
! Please note that TEMP reports can be encoded in various ways in BUFR. Therefore the code
|
|
! below might not work directly for other types of TEMP messages than the one used in the
|
|
! example. It is advised to use bufr_dump first to understand the structure of these messages.
