| 98 | !--------- README TO UNDERSTAND WHAT FOLLOWS (JVO 20) ------- |
|---|
| 99 | ! The lamref variables comes from the Martian model |
|---|
| 100 | ! where the visible one is the one used for computing |
|---|
| 101 | ! and the IR one is used to output scaled opacity to |
|---|
| 102 | ! match instrumental data ... This is done (at least |
|---|
| 103 | ! for now) in the generic, so lamrefir is dummy*! |
|---|
| 104 | |
|---|
| 105 | ! The important one is the VISIBLE one as it will be used |
|---|
| 106 | ! to rescale the values in callcork.F90 assuming 'aerosol' is |
|---|
| 107 | ! at this visible reference wavelenght. |
|---|
| 108 | |
|---|
| 109 | ! *Actually if you change lamrefir here there is a |
|---|
| 110 | ! slight sensitvity in the outputs because of some |
|---|
| 111 | ! machine precision differences that amplifys and lead |
|---|
| 112 | ! up to 10-6 differences in the radiative balance... |
|---|
| 113 | ! This could be good to clean the code but would require |
|---|
| 114 | ! a lot of modifs and to take care ! |
