It contains the subroutines taugbn (where n goes from 1 to 16). taugbn calculates the optical depths and planck fractions per g-value and layer for band n.

Parameters
laytroptropopause layer index (unitless) layer at which switch is made for key species
pavellayer pressures (mb)
coldrycolumn amount for dry air \((mol/cm^2)\)
colamtcolumn amounts of h2o, co2, o3, n2o, ch4,o2, co \((mol/cm^2)\)
colbrdcolumn amount of broadening gases
wxcross-section amounts \((mol/cm^2)\)
tauaeraerosol optical depth
rfratereference ratios of binary species parameter
(:,m,:)m=1-h2o/co2,2-h2o/o3,3-h2o/n2o,4-h2o/ch4, 5-n2o/co2,6-o3/co2
(:,:,n)n=1,2: the rates of ref press at the 2 sides of the layer
facijfactors multiply the reference ks, i,j of 0/1 for lower/higher of the 2 appropriate temperatures and altitudes
jpindex of lower reference pressure
jt,jt1indices of lower reference temperatures for pressure levels jp and jp+1, respectively
selffacscale factor for water vapor self-continuum equals (water vapor density)/(atmospheric density at 296k and 1013 mb)
selffracfactor for temperature interpolation of reference water vapor self-continuum data
