[RegCNET] radiation arrays clarification

[Peter Huszar]

Dear RegCM users

In BATS, I would like to modiofy the net downward shortwave radiation
according to a small module I use for gridpoints with urban landuse
category.
However I am a little bit confused which parameter to change. It is
the fsw1d(i) (the "BATS" array), or I can change straight the
fsw2d(i,j), or the fswa2d(i,j)

The same for the long-way net upward radiation at the surface (flw..)

Thanks a lot for any help
Peter
