Remote Sensing and Ground Measurements of Particle Pollution at UMBC
Research at the University of Maryland, Baltimore County (UMBC), a partner of NOAA’s Cooperative Remote Sensing Science and Technology (CREST) Center, revolves around understanding atmospheric chemistry and physics in the troposphere with remote sensing technology and surface in-situ measurements of gases and aerosols. UMBC Elastic, Raman and Doppler wind lidar provide high resolution information on the altitude dependence of tropospheric aerosols, water vapor and wind to understand meteorological controls in particle pollution variability (local-regional-intercontinental sources), planetary and marine boundary layer structure (wind speed, wind direction, vertical velocity statistics, mixing layer heights and turbulent kinetic energy). In addition, the lidar measurements contribute to accuracy assessments (calibration/validation efforts) of satellite sensors over urban and coastal areas.
Lidar optical properties of aerosols and surface particulate matter (PM10 and PM2.5) measurements, allow us to investigate the physical and chemical properties of aerosols and their influences upon the air quality and solar radiation budget. The lidar profiles allow the derivation of above/below boundary layer optical depth that helps us understand how lofted aerosols may alter the relationship between column optical depth retrievals, and PM2.5 concentrations. Research capabilities of UMBC will be discussed.
