25-Sep-2007

In GEOS-Chem v7-04-12 (as of Sep 2007), we use the older annual emission factors (AEF's) for isoprene.

However, Alex Guenther (personal communication) uses the current isoprene AEF's were obsolete and that we should be using updated isoprene AEF's. Dylan Millet has created an updated AEF file for isoprene but it has not been implemented into the standard GEOS-Chem code yet. (Some folks have already used the new AEF's in their research codes.) The new AEF's are currently scheduled to be implemented in GEOS-Chem beta release v8-01-02.
