Abstract

The upcoming satellite lidar mission CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) will provide a means for observationally based estimates of direct aerosol forcing and an improved empirical basis for assessing indirect aerosol forcing. As the first lidar designed for atmospheric studies to fly in Earth orbit, the LITE (Lidar In-space Technology Experiment) shuttle mission has played an important role in providing testbed experience for CALIPSO. Most importantly, the LITE mission demonstrated that spaceborne lidar provides an effective means for detecting the spatial features of significant regional aerosol concentrations. For lidars operating at both longer and shorter wavelengths (e.g., 1064 nm and 532 nm) a viable calibration ratio approach has been introduced to overcome the difficulty in implementing the Rayleigh normalization approach at longer wavelengths beyond about 800 nm [1]. Moreover, multiple scattering effects and uncertainty assessments in the aerosol retrieval have been combined into an improved aerosol retrieval approach, which was used for the quantitative retrievals of aerosol backscatter and extinction profiles obtained from the LITE 532 nm data [2]. With the impetus provided by the CALIPSO mission, this paper presents the continued analysis of LITE data for 1064 nm aerosol retrievals, building not only on these revised calibration and aerosol retrieval approaches, but also based on improved modeling and the use of auxiliary spectral transmittance information to reduce the uncertainty range for the aerosol extinction-to-backscatter ratio, Sa, for 1064 nm, which is critically important for constraining the aerosol retrievals.
