Abstract

We have developed a pulsed lidar technique for measuring the tropospheric CO₂ concentrations as a candidate for NASA´s planned ASCENDS space mission. We have developed an airborne lidar to demonstrate the measurements from aircraft. In 2010 and 2011we measured atmospheric CO₂ and O₂ column absorptions and line shapes on a series of flights at altitudes from 3-13 km.
