 the array absa(NG02,65) = ka(NG02,5,13) contains absorption coefs at the NG02=12 chosen g-values for a range of pressure levels>~100mb and temperatures. the first index in the array, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 1-5 means that the data are for the corresponding temperature of tref-30, tref-15, tref, tref+15, and tref+30, respectively. the second index, jp, runs from 1 to 13 and refers to the corresponding pressure level in pref (e.g. jp = 1 is for a pressure of 1053.63 mb). the third index, ig, goes from 1 to NG02=12, and tells us which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(ng02, msb02), public absb
 the array absb(NG02,235) = kb(NG02,5,13:59) contains absorption coefs at the NG02=12 chosen g-values for a range of pressure levels< ~100mb and temperatures. the first index in the array, jt, which runs from 1 to 5, corresponds to different temperatures. more specifically, jt = 1-5 means that the data are for the corresponding temperature of tref-30, tref-15, tref, tref+15, and tref+30, respectively. the second index, jp, runs from 13 to 59 and refers to the jpth reference pressure level (see taumol.f for the value of these pressure levels in mb). the third index, ig, goes from 1 to NG02=12, and tells us which g-interval the absorption coefficients are for.
 
real(kind=kind_phys), dimension(ng02, msf02), 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 NG02=12).
 
real(kind=kind_phys), dimension(ng02, mfr02), public forref
 the array forref contains the coefficient of the water vapor foreign-continuum (including the energy term). the first index refers to reference temperature (296,260,224,260) and pressure (970,475,219,3 mbar) levels. the second index runs over the g-channel (1 to NG02=12).
