Last change on this file since 5418 was 4853, checked in by idelkadi, 9 months ago

Ecrad update in LMDZ / Implementation of Ecrad double call in LMDZ

version 1.6.1 (commit 210d7911380f53a788c3cad73b3cf9b4e022ef87)
interface routines between lmdz and ecrad grouped in a new "lmdz" directory
double call method redesigned so as to go through the Ecrad initialization and configuration part only once for the entire simulation
clean-up in the read.F routine: delete unitules arguments
modification of default gas model in namelist (default: ECCKD)
