Changeset 2947 for LMDZ5/trunk/libf

Timestamp:

Jul 13, 2017, 6:43:58 PM (7 years ago)

Author:

dcugnet

Message:

• The "units" attribute of SST variable is now checked to allow celcius degrees to kelvins conversion if required.
• Few cosmetic changes for output text file to make it more readable (and help to detect if ce0l has really done what was expected).

File:

• LMDZ5/trunk/libf/dynphy_lonlat/phylmd/limit_netcdf.F90 (modified) (14 diffs)
