AB: The NASA Langley Research Center (LaRC) airborne High Spectral Resolution Lidar (HSRL) was deployed on the NASA LaRC B-200 King Air aircraft and measured profiles of aerosol extinction, backscatter, and depolarization during the Megacity Initiative: Local and Global Research Observations (MILAGRO) Campaign in March 2006. The HSRL collected approximately 55 hours of data over 15 science flights, which were coordinated with the Sky Research J-31 aircraft (5 flights), the DOE G-1 aircraft (6 flights), and the NCAR C-130 aircraft (4 flights). This coordinated effort in MILAGRO provides the first opportunity to evaluate the HSRL aerosol extinction and optical thickness profiles with corresponding profiles derived from the other airborne measurements: 1) the 14 channel NASA Ames Airborne Tracking Sunphotometer (AATS-14) on the J-31 and the in situ nephelometer measurements of aerosol scattering and Particle Soot Absorption Photometer (PSAP) measurements of aerosol absorption from the Hawaii Group for Environment and Atmospheric Research (HiGEAR) on the C-130. This study will include comparisons of aerosol extinction from these three techniques in cases where the HSRL flew directly over the AATS-14 and HiGEAR instruments while they measured aerosol extinction profiles. The results are used in assessing the uncertainty of the HSRL extinction profiles. Column aerosol optical depth (AOD) derived from the HSRL measurements is also compared with AOD derived from Moderate Resolution Imaging Spectroradiometer (MODIS) measurements acquired on the Terra and Aqua spacecraft and from Aerosol Robotic Network (AERONET) ground-based Sun photometer measurements.
