! 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.
!
