radiation_AR4.F @ 1244

Last change on this file since 1244 was 1231, checked in by lguez, 15 years ago

These are changes related to ozone in radiative transfer computations:

-- Moved "max(ozonecm, 1e-12)" from procedure "radlwsw" to procedure

"ozonecm".

-- Removed ratio "p_surface / p_reference" in the computation of

"pozon" in "radlwsw".

-- Removed ratio "p_reference / p_surface" in the computation of

"zoz" in "SW_LMDAR4" and "SW_AEROAR4".

-- Removed ratio "mass of air / mass of ozone" in the computation of

"zoz" in "LW_LMDAR4".
