CARESSURFMET

Carbonaceous Aerosol and Radiation Effects Study (CARES) - Surface Meteorological Sounding

26 May 2010 - 7 July 2010

Lead Scientist: Rahul Zaveri

Observatory: AAF , OSC

The primary objective of the CARES is to study the evolution of carbonaceous aerosols and their optical and hygroscopic properties in the Sacramento urban plume as it is advected to the northeast. Carbonaceous aerosols, which include black carbon (BC), urban primary organic aerosols (POA), biomass burning aerosols (BBA), and secondary organic aerosols (SOA) from both urban and biogenic precursors, play a major role in the direct and indirect radiative forcing of climate. However, significant knowledge gaps and uncertainties still exist in the process level understanding of: 1) SOA formation, 2) BC mixing state evolution, and 3) the optical and hygroscopic properties of fresh and aged carbonaceous aerosols. The proposed instruments will provide essential meteorological information about atmospheric structure and transport.
