Changeset 2245 for trunk/LMDZ.GENERIC/libf

Timestamp:

Feb 24, 2020, 6:55:50 PM (5 years ago)

Author:

Message:

+ Add a 'versH2H2cia' int key in callphys that allows two values (2011 or 2018) to

deal with updated HITRAN file (for interpolateH2H2.F90) from 2018 that includes the
H2H2 dimer from Fletcher et al. 2018, useful for giant planets.
Retrocompatibility is ok, default value to 2011.
