| 14 | ! Purpose |
|---|
| 15 | ! ------- |
|---|
| 16 | ! Interface subroutine to YAMMS model for LMD PCM. |
|---|
| 17 | ! |
|---|
| 18 | ! The subroutine computes the microphysics processes for a single vertical column. |
|---|
| 19 | ! - All input vectors are assumed to be defined from GROUND to TOP of the atmosphere. |
|---|
| 20 | ! - All output vectors are defined from GROUND to TOP of the atmosphere. |
|---|
| 21 | ! - Only tendencies are returned. |
|---|
| 22 | ! |
|---|
| 23 | ! @important |
|---|
| 24 | ! The method assumes global initialization of YAMMS model (and extras) has been already |
|---|
| 25 | ! done elsewhere. |
|---|
| 26 | ! |
|---|
| 27 | ! @warning |
|---|
| 28 | ! Microphysical tracers from physics must be in X/kg_of_air and convert into X/m2 for microphysics. |
|---|
| 29 | ! |
|---|
| 30 | ! @warning |
|---|
| 31 | ! We suppose a given order of tracers (1. mu_m0as, 2. mu_m3as, 3. mu_m0af, 4. mu_m3af)! |
