|---|
| 5 | ! The subroutines CMBGB1->CMBGB16 input the absorption coefficient |
|---|
| 6 | ! data for each band, which are defined for 16 g-points and 16 spectral |
|---|
| 7 | ! bands. The data are combined with appropriate weighting following the |
|---|
| 8 | ! g-point mapping arrays specified in RRTMINIT. Plank fraction data |
|---|
| 9 | ! in arrays FRACREFA and FRACREFB are combined without weighting. All |
|---|
| 10 | ! g-point reduced data are put into new arrays for use in RRTM. |
|---|
| 11 | |
|---|
| 12 | ! BAND 1: 10-250 cm-1 (low - H2O; high - H2O) |
