radiation_AR4.F @ 1106

Last change on this file since 1106 was 1106, checked in by lguez, 16 years ago
"comconst.h", and "comgeom2.h" are now both fixed and free form. Removed calls to procedure "flush". Corrected kinds of constants which appeared as arguments to "min" or "max" (all arguments are now of the same type and kind).
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`

6014	C --------
6015	C THIS ROUTINE COMPUTES THE TRANSMISSION FUNCTIONS FOR ALL THE
6016	C ABSORBERS (H2O, UNIFORMLY MIXED GASES, AND O3) IN ALL SIX SPECTRAL
6017	C INTERVALS.
6018	C
6019	C METHOD.
6020	C -------
6021	C
6022	C 1. TRANSMISSION FUNCTION BY H2O AND UNIFORMLY MIXED GASES ARE
6023	C COMPUTED USING PADE APPROXIMANTS AND HORNER'S ALGORITHM.
6024	C 2. TRANSMISSION BY O3 IS EVALUATED WITH MALKMUS'S BAND MODEL.
6025	C 3. TRANSMISSION BY H2O CONTINUUM AND AEROSOLS FOLLOW AN
6026	C A SIMPLE EXPONENTIAL DECREASE WITH ABSORBER AMOUNT.
