Principal Investigator / Author(s): Allen Goldstein

Contractor: UC Berkeley

Contract Number: 09-339


Research Program Area: Atmospheric Processes

Topic Areas: Field Studies, Natural (Biogenic) Sources


Abstract:

Biogenic volatile organic carbon (BVOC) inventories are critical for ozone and aerosol formation modeling and thus they are critical inputs to state implementation plans (SIP) for ozone and particulate matter. Our current Biogenic Emission Inventories through Geographic Information System (BEIGIS) simulation platform relies on land cover databases developed from older satellite data, scaling from leaf and needle level emissions data to canopy and grid level emissions which have minimal confirmation. In addition ARB lacks a regional assessment of BVOC species concentrations that would validate BEIGIS outputs for California. The federal Environmental Protection Agency (EPA) Model of Emissions of Gases and Aerosols from Nature (MEGAN) produces significantly different BVOC emissions than BEIGIS. These uncertainties need to be resolved. This project will would collect regional concentrations data for the full suite of BVOC species and would provide additional insights in terms of new land cover databases, as well as, assist the proper scaling methodology. The results of this project would strengthen ARB BVOC inventory and improve the modeling of ozone and aerosols in ARB SIP.
