| − | == Overview == | + | == MEGAN 3.0 == |
| | | | |
| − | GEOS-Chem has used three versions of the MEGAN biogenic emissions. These are now all described on separate wiki pages.
| + | An implementation of MEGAN 3.0 is currently a [https://github.com/geoschem/geos-chem/issues/1026 requested feature for GEOS-Chem development]. |
| | | | |
| − | === MEGAN v2.0 biogenic emissions ===
| + | == MEGAN v2.1 plus Guenther 2012 biogenic emissions == |
| | | | |
| − | The [[MEGAN v2.0 biogenic emissions]] are now obsolete. They were used in [[GEOS-Chem v8-02-03]] and prior versions.
| + | GEOS-Chem currently uses the [[MEGAN v2.1 plus Guenther 2012 biogenic emissions|MEGAN 2.1 biogenic emissions with updates from Guenther (2012)]]. The emissions fed into GEOS-Chem by the [https://hemco.readthedocs.io Harmonized Emissions Component (HEMCO)] extension. |

| + | |
| − | | + | |
| − | The [[MEGAN v2.1 biogenic emissions]] were used in [[GEOS-Chem v8-02-04]] through [[GEOS-Chem v9-02]]. They were retired with the advent of the [[HEMCO emissions component]] in [[GEOS-Chem v10-01]].
