|---|
| 10 | c -------- |
|---|
| 11 | c Subroutine designed to call the main canonic |
|---|
| 12 | c radiative transfer subroutine "lwmain" et "swmain" |
|---|
| 13 | c to compute radiative heating and cooling rate and |
|---|
| 14 | c radiative fluxes to the surface. |
|---|
| 15 | c |
|---|
| 16 | c These calculations are only valid on the part of the atmosphere |
|---|
| 17 | c where Local Thermal Equilibrium (NLTE) is verified. In practice |
|---|
| 18 | c The calculations are only performed for the first "nlaylte" |
|---|
| 19 | c parameters (nlaylte is calculated by subroutine "nlthermeq" |
|---|
| 20 | c and stored in common "yomlw.h" |
|---|
| 21 | c |
|---|
| 22 | c |
|---|
| 23 | c |
|---|
| 24 | c The purpose of this subroutine is |
|---|
| 25 | c 1) Make some initial calculation at first call |
|---|
| 26 | c 2) Split the calculation in several sub-grid |
|---|
| 27 | c ("sub-domain") to save memory and |
|---|
| 28 | c be able run on a workstation at high resolution |
|---|
| 29 | c The sub-grid size is defined in dimradmars.h |
|---|
| 30 | c 3) call "lwmain" and "swmain" |

| 35 | c Francois Forget / Christophe Hourdin |
|---|
| 36 | c |
|---|
| 37 | c This version modified to only calculate radiative tendencies over |
|---|
| 38 | c layers 1..NFLEV (set in dimradmars.h). Returns zero for higher |
|---|
| 39 | c layers, if any. |
|---|
| 40 | c In other routines, nlayermx -> nflev. |
