source: LMDZ6/trunk/libf/phylmd/phyetat0.F90 @ 3776

Last change on this file since 3776 was 3756, checked in by oboucher, 4 years ago

The fraction of SW down radiation that is diffuse is extracted from radlwsw.F90 and passed on to pbl_surface for inclusion in fields_out for transfer to ORCHIDEE if it requested in input file coupling_fields.def. Hence there is nothing automatic here. The fraction of SW down radiation is also added as a diagnostic. To satisfy the case when this new quantity is used in ORCHIDEE, then it is added in the restart (and read in case it is there).
