Deriving Information on Surface Conditions from Column
and Vertically Resolved Observations Relevant to Air Quality

• Airborne measurements (NASA P-3B) in the United States to improve the ability of satellite-based observations to diagnose near-surface air quality conditions.
  Measurements were made in:
  • Baltimore-Washington D.C. area, June-July 2011
  • California Central Valley, January-February 2013
  • Houston area, September 2013
  • Denver, July - August 2014
• LARGE Publications & Findings:
  • Airborne observations of aerosol extinction by in situ and remote-sensing techniques: Evaluation of particle hygroscopicity (Ziemba et al., GRL)
  • Correlation between satellite AOD and surface PM2.5 (Crumeyrolle, ACP)
  • Impacts of aerosol loading, composition, and water uptake on aerosol extinction variability
    (Beyersdorf, ACP)
