This dataset consists of a series of attenuated atmospheric backscatter profiles that were measured at 1572 nm by the CO2 Sounder lidar during the eight flights of the 2017 ASCENDS/ABoVE (Active Sensing of CO2 Emission over Nights, Days, and Seasons mission, Arctic Boreal Vulnerability Experiment) airborne campaign. In addition to measuring the column average CO2 mixing ratio from the signals reflected by the ground, the CO2 Sounder lidar also recorded the height-resolved attenuated atmospheric backscatter profiles beneath the aircraft. These vertical attenuated atmospheric backscatter profiles are sampled a 15-m vertical spacing and averaged over 1-second along the flight path (~200 m). The details of the signal processing and estimated signal to noise ratio are given in the report posted along with the data.
