Regarding the CLM4 in WRF

[tindori.jaydeep000@gmail.]

Dear All,
I am curious to know that the CLM4 is coupled with the WRF-ARW a long ago. Does it include the SNICAR (SNow and Ice Aerosol Radiation). It is mentioned in the official note that CLM4 is coupled with SNICAR (https://www2.cesm.ucar.edu/models/cesm1.0/clm/Short_CLM4_SciDescription.pdf).

Thanks

I think it is in /phys/module_sf_clm.F(After Line 575).

Hello haiqingsong,
Thanks for your reply.
My question was, is this version of clm include SINCAR? There is not update in the manual about it. And not flags for SNICAR installation.

This version of CLM in WRF has SNICARMod(/phys/module_sf_clm.F(After Line 23350)). But I don't know if CLM contains the full SNICAR.

CLM3.5 was coupled with WRF and released in 2013 (WRFV3.5). A few features of CLM4 were added to this version of CLM (CLM3.5) but no specific issue was addressed regarding SNICAR in CLM4. I suppose that SNICAR in WRF remains the same as that in CLM3.5. If SNICAR was updated in CESM-CLM4, I believe these updates are not included in WRF.
