21 | ! Purpose |
---|
22 | ! ------- |
---|
23 | ! Calculates longwave optical constants at each level. For each |
---|
24 | ! layer and spectral interval in the IR it calculates WBAR, DTAU |
---|
25 | ! and COSBAR. For each level it calculates TAU. |
---|
26 | ! |
---|
27 | ! TAUCUMI(L,LW) is the cumulative optical depth at level L (or alternatively |
---|
28 | ! at the *bottom* of layer L), LW is the spectral wavelength interval. |
---|
29 | ! |
---|
30 | ! TLEV(L) - Temperature at the layer boundary (i.e., level) |
---|
31 | ! PLEV(L) - Pressure at the layer boundary (i.e., level) |
