Hello everyone,
It seems that the CLM has not coupled with RegCM completely. You can find the albedo used by the radiation parametrization is calculated by the ./batslib/mod_bats_mtrxbats.F90 which is part of the BATS not CLM. And the albedo calculated by the CLM has not been used by the CLM.
Thank you very much!
Sincerely,
Sun Chao
