| 8 | ! The subroutines CMBGB16->CMBGB29 input the absorption coefficient |
|---|
| 9 | ! data for each band, which are defined for 16 g-points and 14 spectral |
|---|
| 10 | ! bands. The data are combined with appropriate weighting following the |
|---|
| 11 | ! g-point mapping arrays specified in RRTMG_SW_INIT. Solar source |
|---|
| 12 | ! function data in array SFLUXREF are combined without weighting. All |
|---|
| 13 | ! g-point reduced data are put into new arrays for use in RRTMG_SW. |
|---|
| 14 | |
|---|
| 15 | ! BAND 16: 2600-3250 cm-1 (low key- H2O,CH4; high key - CH4) |
