[RegCNET] Sub-BATS scheme

[Simon Krichak]

Hi,

I am still having problems with using the Sub-BATS scheme. The model runs 
fine and I obtain reasonable results  - over sea surface. Over land poits my 
results are absolutely wrong hovever - for instance simulated t2m 
temperatures are  at least for about 5-8 deg lower than they are in the 
control version.
Something is wrong apparently.
Any hint please.

Simon
