Short summary
Here we report on measurements made with an improved CO2 Sounder lidar during the ASCENDS 2014 and 2016 airborne campaigns. The results from the 2016 airborne lidar retrievals show precisions of ~ 0.8 parts per million (ppm) with 1 s averaging over desert surfaces. The results from both campaigns showed the mean values of XCO2 retrieved from the lidar consistently agreed with those based on the in situ sensor to within 1 ppm.
