| | 20 | ============== |
| | 21 | - No new tickets |
| | 22 | - suggestion by Christophe & Vincent: some miissing error messages in initracer.F; additional checks needed |
| | 23 | + mention by Romain of misleading mesage when some tracers in traceur.def don't match the flags in callphys.def |

| | 26 | ============= |
| | 27 | - #25 closed |
| | 28 | |
| | 29 | Hot topics: |
| | 30 | ========== |
| | 31 | |
| | 32 | * Water cycle conservation & stability (Joseph) |
| | 33 | - bug with watercaptag and sub-timestepping identified (in 1D). There might be other issues. |
| | 34 | Joseph will commit the correction. |
| | 35 | |
| | 36 | * Improving the dust cycle (Antoine) |
| | 37 | - tuning the combined dust & water cycle. For now too wet. Drying the water cycle will involve changing |
| | 38 | thermal inertia and albedo of frost towards more realistic values. The contact parameter function could |
| | 39 | also be improved. |
| | 40 | |
| | 41 | * Non-orographic GW with the thermosphere setup (Jiandong) |
| | 42 | - Looked thoroughly at the equations and way they are written and used in the code. |
| | 43 | Proposes some improvements about intermediate computations of altitudes and BV and scale height, |
| | 44 | and more stable evaluation of rho (including variation of r). |
| | 45 | Overall yields a good impact on the effect of the parametrization (more constrained to act on |
| | 46 | lower altitudes in the thermosphere than the model top). |
| | 47 | - Other big problem: there was a mix-up between increment and tendency due to the problem. |
| | 48 | - Retuning of the parametrization required, versus MCS and Maven data. |
| | 49 | |
| | 50 | Jean-Yves: |
| | 51 | - working on the ionosperic version of the GCM to compute escape. |
| | 52 | |
| | 53 | Gabriella: |
| | 54 | - running with iphysiq=5 or 10, several Mars Years. Looking at the water at given altitudes |
| | 55 | with some spikes in the north during summer, but perhaps looking at columns to confirm/invalidate |
| | 56 | might be better. |
