SP2 Deployment at Boston College-Aerodyne led Coated Black Carbon Study (BC4)
25 March 2015 - 30 April 2015
Lead Scientist: Timothy Onasch
Observatory: OSC
The main objective of the Boston College-Aerodyne led laboratory study (BC4) is to measure the optical properties of black carbon (BC) particles coated with secondary organic and inorganic material and to achieve optical closure with model predictions. The measurements of single particle BC mass and population mixing states provided by a single particle soot photometer (SP2) will be central to the laboratory-based study. Specifically, with the DOE ARM SP2 instrument as part of the BC4 project, we would expect to address the following scientific questions:
- What is the mass-specific absorption coefficient (MAC) as a function of secondary organic and inorganic material coatings?
- What is the spread in the population mixing states within our carefully generated laboratory particles?
- How does the SP2 instrument respond to well characterized, internally mixed BC-containing particles?
