Dear Andreas,

Thank you for your suggestions. I’m using model with turned on dependency of the heat conductivity on the soil water content (itype_heatcond = 2, do you mean this?) and itype_conv = 0.

And in case we are talking about other surface schemes, are there something like starter package or description about how to run CCLM coupled with them? I’ve read about them, but has no idea how to start with them.
