! Purpose. |
| 13 |
! This routine computes the shortwave radiation fluxes in two |
| 14 |
! spectral intervals following Fouquart and Bonnel (1980). |
| 15 |
|
| 16 |
! Method. |
| 17 |
! 1. Computes absorber amounts (swu) |
| 18 |
! 2. Computes fluxes in 1st spectral interval (SW1S) |
| 19 |
! 3. Computes fluxes in 2nd spectral interval (SW2S) |
| 20 |
|
| 21 |
! Reference. |
| 22 |
! See radiation part of the ECMWF research department |
| 23 |
! documentation, and Fouquart and Bonnel (1980) |
