Remotely-Sensed Aerosol Optical Properties Retrieved from a High Spectral Resolution Lidar (HSRL) and Comparisons with in-situ Measurements During the 2019 FIREX-AQ Field Campaign
Abstract
The NASA Langley Research Center's High Spectral Resolution Lidar with Differential Absorption Lidar (HSRL-DIAL) instrument was flown on the NASA DC-8 aircraft during the Fire Influence on Region to Global Environments and Air Quality (FIREX-AQ; https://www.esrl.noaa.gov/csl/projects/firex-aq/) field campaign. An overview of aerosol optical properties retrieved from the HSRL-DIAL instrument for a variety of wildfires sampled during the western U.S. portion of the campaign are reviewed. Retrievals of aerosol depolarization, lidar ratio, color ratio, spectral depolarization, and aerosol optical thickness are analyzed and compared to measurements of microphysical properties and gas phase emissions collected during in-situ sampling. Optical properties as a function of altitude and injection height are explored.
