Variables

integer, public msa23
 msa23=65
 
coefficients to compute tau, ssa, asy for rain drop and snowflake
integer, public msf23
 msf23=10
 
integer, public mfr23
 mfr23=3
 
real(kind=kind_phys), dimension(mfr23, ng23), public forref
 
real(kind=kind_phys), dimension(msa23, ng23), public absa
 the array absa(65,NG23) (ka(5,13,NG23)) contains absorption coefs at the 16 chosen g-values for a range of pressure levels> ~100mb, temperatures, and binary species parameters (see taumol.f for definition). the first index in the array, js, runs from 1 to 9, and corresponds to different values of the binary species parameter. for instance, js=1 refers to dry air, js = 2 corresponds to the paramter value 1/8, js = 3 corresponds to the parameter value 2/8, etc. the second index in the array, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 3 means that the data are for the reference temperature tref for this pressure level, jt = 2 refers to tref-15, jt = 1 is for tref-30, jt = 4 is for tref+15, and jt = 5 is for tref+30. the third index, jp, runs from 1 to 13 and refers to the jpth reference pressure level (see taumol.f for these levels in mb). the fourth index, ig, goes from 1 to 10, and indicates which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(msf23, ng23), public selfref
 the array selfref contains the coefficient of the water vapor self-continuum (including the energy term). the first index refers to temperature in 7.2 degree increments. for instance, jt = 1 refers to a temperature of 245.6, jt = 2 refers to 252.8, etc. the second index runs over the g-channel (1 to 10).
 
real(kind=kind_phys), dimension(ng23), public rayl
 rayleigh extinction coefficient at all v
 
real(kind=kind_phys), parameter, public givfac = 1.029
 average giver et al. correction factor for this band.
