arbcombo -- Tomorrows ARB Research Seminar: Source Speciation of Central Valley GHG Emissions Using In-Situ Measurement of VOCs

Allen Goldstein, PhD
University of California, Berkeley and
Mark Fischer, PhD
Lawrence Berkeley National Laboratory.

*NEW TIME: Thursday, August 25, 2016 at 10:00 a.m., PDT
(WEBCAST)
Sierra Hearing Room, 2nd Floor, Cal/EPA Building
1001 I Street, Sacramento, California

*Presentation will be available for downloading, morning of the
seminar

Reducing greenhouse gas (GHG) emissions requires knowledge of the
sources and activities which emit GHGs. California's Central
Valley has a number of agricultural and natural sources of GHGs
in addition to urban, anthropogenic sources. This work
investigates the seasonal variability of CH₄ and N₂O
source apportionment from year-long measurements of GHGs, CO, and
a suite of VOCs in Walnut Grove, about 23 miles south of downtown
Sacramento, from summer 2012 through early fall 2013. We apply
the statistical technique of positive matrix factorization (PMF)
on the combined GHG - VOC data set over seven separate periods
that are representative of broad seasonal patterns observed in
the region. We also compare our results to inverse modeling
estimates at WGC for the same time-period. For more go to the
