Dear Mahmoud,
Let me relook to Graziano email;

has not found a snow file to use to initialize the snow field at model
start (i.e. you run the model for some years, let the snow accumulate,
then extract the last timestep of the snow from the SRF output to have
the production run start with a realistic snow cover). 2) The chym (and this is off-topic) reads the snow field from the regcm,
but the code there search for the variable "scv", while in the 4.4 code
we have changed the variable name to "snv" to respect the CORDEX convention. Add for this the following line: istatus = nf_inq_varid(lun,'scv',scode)
+       if (istatus.ne.nf_noerr) istatus = nf_inq_varid(lun,'snv',scode) at line 2115 of file museo.f in the libmv library of chym. Ciao! --
