The array KA 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 16, and indicates ! which g-interval the absorption coefficients are for. ! ----------------------------------------------------------------- ! ----------------------------------------------------------------- !
