Abstract:

Accurate global measurements of tropospheric Carbon Dioxide abundance to the “parts per million” (ppm) level is required to better quantify processes that regulate CO2 exchange between atmosphere, land and ocean. To measure CO2 globally NASA has planned the ASCENDS mission, Active Sensing of CO2 Emissions over Nights, Days and Seasons. We report on an airborne laser-based remote sensing instrument we have developed at NASA-GSFC as a candidate for the ACENDS mission. Preliminary analyses of data from initial flight testing to 13 km altitude indicates a CO2 mixing ratio of 396 ppm from CO2 column abundance where in situ sensors determine 390 ppm mixing ratio.
