To avoid overly hot SSTs in some tropical areas, changes being made to prescribe downwelling shortwave and longwave radiation. The net downward shortwave at the surface is used directly by the model, but the longwave requires a minor change to the model code. I've changed:
hl=0.985*5.67d-8*(surf_temp**4.0)*(0.39-0.05*vap**0.5)*(1.0-0.6d-4*cloud(idmet)**2.0) !original codes Longwave
to
hl=0.985*5.67d-8*(surf_temp**4.0)-lw_rad_down0 !Longwave
note, I'm not sure why humiditry would have been used in tgeh original calculation. Is this a way at getting towards skin temperature from tghe model's surface level temperature?
