متن کاملSources of organic aerosol investigated using organic compounds as tracers measured during CalNex in Bakersfield
[1] To investigate the major sources of summertime organic aerosol (OA) and provide insights into secondary organic aerosol (SOA) formation, positive matrix factorization analysis was performed on a large set of organic species measured during the California at the Nexus of Air Quality and Climate Change (CalNex) campaign in Bakersfield, CA. Six OA source factors were identified, including one ...
متن کاملThe glyoxal budget and its contribution to organic aerosol for Los Angeles, California, during CalNex 2010
[1] Recent laboratory and field studies have indicated that glyoxal is a potentially large contributor to secondary organic aerosol mass. We present in situ glyoxal measurements acquired with a recently developed, high sensitivity spectroscopic instrument during the CalNex 2010 field campaign in Pasadena, California. We use three methods to quantify the production and loss of glyoxal in Los Ang...
متن کاملAerosol optical properties at Pasadena, CA during CalNex 2010
Aerosol optical properties measured at the Pasadena, CA site during the CalNex field campaign in May eJune 2010 are summarized. Average measurements of PM2.5 aerosol extinction, scattering, absorption coefficients, and single scattering albedo (bext, bscat, babs and SSA) at l 1⁄4 532 nmwere 62 Mm 1, 58 Mm 1, 4 Mm 1, and 0.92, respectively. The aerosol optical densities were 5 times lower than d...
