  • Update of Ecrad in LMDZ The same organization of the Ecrad offline version is retained in order to facilitate the updating of Ecrad in LMDZ and the comparison between online and offline results. version 1.6.1 of Ecrad (https://github.com/lguez/ecrad.git)
  • Implementation of the double call of Ecrad in LMDZ

1! Configuration namelists for ecRad radiation scheme
2!
3! The "radiation_driver" namelist controls the behaviour of the driver
4! routine, including parallelization options and overriding numbers
5! read from the NetCDF input file. The "radiation" namelist controls
6! the behaviour of the radiative transfer algorithm itself. Any line
7! prefixed by "!" is ignored. If a namelist parameter is missing then
8! ecRad will use a default value.  For most parameters you can see
9! what ecRad has used from the output printed to the terminal when it
10! runs.

12! The "iverbose*" parameters specify the verbosity level: 0=none,
