== Top-down Findings Germane to GEOS-Chem Inventories (please add yours!) ==
  
Here is the list of updates that are slated to be added to GEOS-Chem in the next few releases:
+
Science findings from top-down studies that have implications for inventories used in GEOS-Chem (e.g., an inferred high or low bias or other such issue) can be compiled in [[Inventory Findings|this table]]. Please add any findings, either from your group or from other groups, that you feel the GEOS-Chem community should be aware of in using these inventories.

'''Evaluation of the global oceanic isoprene source and its impacts on marine organic carbon aerosol'''. Arnold SR, Spracklen DV, Williams J, Yassaa N, Sciare J, Bonsang B, Gros V, Peeken I, Lewis AC, Alvain S, Moulin C. ATMOSPHERIC CHEMISTRY AND PHYSICS, Volume: 9, Issue: 4, Pages: 1253-1262, Published: 2009. We have combined the first satellite maps of the global distribution of phytoplankton functional type and new measurements of phytoplankton-specific isoprene productivities, with available remote marine isoprene observations and a global model, to evaluate our understanding of the marine isoprene source and its impacts on organic aerosol abundances. Using satellite products to scale up data on phytoplankton-specific isoprene productivity to the global oceans, we infer a mean "bottom-up" oceanic isoprene emission of 0.31 +/- 0.08 (1 sigma) Tg/yr. By minimising the mean bias between the model and isoprene observations in the marine atmosphere remote from the continents, we produce a "top-down" oceanic isoprene source estimate of 1.9 Tg/yr. We suggest our reliance on limited atmospheric isoprene data, difficulties in simulating in-situ isoprene production rates in laboratory phytoplankton cultures, and limited knowledge of isoprene production mechanisms across the broad range of phytoplankton communities in the oceans under different environmental conditions as contributors to this difference between the two estimates. Inclusion of secondary organic aerosol (SOA) production from oceanic isoprene in the model with a 2% yield produces small contributions (0.01-1.4%) to observed organic carbon (OC) aerosol mass at three remote marine sites in the Northern and Southern Hemispheres. Based on these findings we suggest an insignificant role for isoprene in modulating remote marine aerosol abundances, giving further support to a recently postulated primary OC source in the remote marine atmosphere.

Latest revision as of 15:29, 22 July 2022

The purpose of this Working Group is to provide a forum to discuss current and new developments in GEOS-Chem associated with land-atmosphere and ocean-atmosphere sources, sinks, and fluxes of trace gases and aerosols.

All users interested in adding/updating the GEOS-Chem emissions inventories are encouraged to subscribe to the emissions email list (click on the link in the contact information section below).

Top-down Findings Germane to GEOS-Chem Inventories (please add yours!)

Science findings from top-down studies that have implications for inventories used in GEOS-Chem (e.g., an inferred high or low bias or other such issue) can be compiled in this table. Please add any findings, either from your group or from other groups, that you feel the GEOS-Chem community should be aware of in using these inventories.
