| | 68 | Waiting for the first result with the 39-layers configuration. |
| | 69 | |
| | 70 | After the General Assembly of ESM2025, pisces emissions seems to be too high... In fact, there was a problem of units conversion (mostly because of a misunderstanding of input units (mol N rather than mol N,,2,,O). |
| | 71 | |
| | 72 | Nicolas asked if lightning is implemented because it seems to have an total emission between 0.5 and 2 Tg/Nyr. |
| | 73 | |
| | 74 | Some works will be presented during the N,,2,,O workshop in Toulouse from July, 6th to 8th. |
| | 75 | |
| | 76 | __//**To DO**//__ |
| | 77 | * Analyse the vertical profile when the 39-layers configuration of one year is done. |
| | 78 | * + See Didier for the next steps. |
| | 79 | * Re-compute the calculation with the good value of pisces emissions. |
| 81 | | * Notebook **Budget_inventories** : total budget of N2O emissions (in tables), differences found between outputs INCASFLX and calculations in notebook (with mask, area and change units), different charts (by latitude, by land/ocean part, with histograms...) |
