Source Speciation of Central VAlley GHG EMissions Using IN-Situ Measurement of VOCs

When: Thursday, August 25, 2016 1:30 pm, PDT (WEBCAST)

Where: Sierra Hearing Room, 2nd Floor, Cal/EPA Building 1001 I Street, Sacramento, CA

What: 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 announcement at:
