Dear RegCM users,

i am digging the code a bit in order to achieve better understanding what is passed to the BATS surface scheme.

I found that in version 4.4.5.5. (Main/batslib/mod_bats_common.F90) the potential temperature is passed.

call c2l_gs(lndcomm,lm%thatm,ts0) (where lm%thatm carries atms%thx3d)

In the latest version 4.4.5.8. this is changed to

call c2l_gs(lndcomm,lm%sfta,ts0), (where m%sfta carries atms%ts2d, i.e. "normal" temperature.

The same is true for versions 4.5-rc5 compared to version 4.5-rc10.

In both cases (whether theta or t are passed to BATS), they are treated as temperature in further.

Am I missing something?

Thanks a lot for the clarification!

With kind regards

Peter
