! Description: read and print radiosonde data from TEMP BUFR messages.
! If available this version also lists the position information from the WMO list
! (now OSCAR/Surface) appended to the reports by ECMWF
!
! Author: Bruce Ingleby
!
! 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.
