| 22 | ! Comments: |
|---|
| 23 | !---------- |
|---|
| 24 | ! - Adaptation of the water ice clouds scheme (with specific microphysics) of Montmessin, Navarro et al. |
|---|
| 25 | ! |
|---|
| 26 | ! - Microphysics subroutine is improvedCO2clouds.F |
|---|
| 27 | ! |
|---|
| 28 | ! - There is a time loop specific to cloud formation due to timescales smaller than the GCM integration timestep |
|---|
| 29 | ! |
|---|
| 30 | ! - The microphysics time step is a fraction of the physical one |
|---|
| 31 | ! |
|---|
| 32 | ! - The CO2 clouds tracers (co2_ice, ccn mass and concentration) are sedimented at each microtimestep. pdqs_sedco2 |
|---|
| 33 | ! keeps track of the CO2 flux at the surface |
|---|
| 34 | ! |
|---|
| 35 | ! - The subgrid Temperature distribution is modulated (0 or 1) by Spiga et al. (GRL 2012) |
|---|
| 36 | ! |
|---|
| 37 | ! - Saturation Index to account for GW propagation or dissipation upwards |
|---|
| 38 | ! |
|---|
| 39 | ! - 4D and column opacities are computed using Qext values at 1µm |
