Objective:
The objective(s) of this project is to make and use measurements of light absorption and extinction by particles, in conjunction with other particle measurements, during the CalNex 2010 field campaign to (1) quantitatively characterize particulate emissions from ocean going vessels in the regulated waters along the California coast; (2) characterize the variability in the mass absorption coefficient for black carbon particles in the atmosphere, and to work towards understanding the origin of this variability; and (3) investigate variability in sources of black carbon in the near-shore marine boundary layer.
