The Promise of Spaceborne High Spectral Resolution Lidar

Remote detection of backscatter, extinction, and the lidar ratio from aerosols and clouds provides important understanding of the impacts of pollution, such as smoke, on the climate system. Spaceborne high spectral resolution lidar (HSRL), or similar observations, have been a decades-long goal of the scientific community. Baars et al. [2021] present first results from the Atmospheric Laser Doppler Instrument (ALADIN) HSR Doppler lidar onboard the Aeolus satellite, through detection of a smoke plume transported from California to over central Europe. While these should be considered preliminary results, they demonstrate the long-awaited potential of spaceborne HSRL and hopefully signal that more…
