Airborne measurements of CO2 column absorption and range using a pulsed direct-detection integrated path differential absorption lidar.
We report on airborne CO(2) column absorption measurements made in 2009 with a pulsed direct-detection lidar operating at 1572.33 nm and utilizing the integrated path differential absorption technique. We demonstrated these at different altitudes from an aircraft in July and August in flights over four locations in the central and eastern United States. The results show clear CO(2) line shape a...
متن کاملAirborne Measurements of CO2 Column Concentration and Range Using a Pulsed Direct-Detection IPDA Lidar
We have previously demonstrated a pulsed direct detection IPDA lidar to measure range and the column concentration of atmospheric CO2. The lidar measures the atmospheric backscatter profiles and samples the shape of the 1,572.33 nm CO2 absorption line. We participated in the ASCENDS science flights on the NASA DC-8 aircraft during August 2011 and report here lidar measurements made on four flig...
متن کاملAtmospheric CO2 Column Measurements with an Airborne Intensity-Modulated Continuous-Wave 1.57-micron Fiber Laser Lidar
The 2007 National Research Council (NRC) Decadal Survey on Earth Science and Applications from Space recommended Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) as a mid-term, Tier II, NASA space mission. ITT Exelis, formerly ITT Corp., and NASA Langley Research Center have been working together since 2004 to develop and demonstrate a prototype Laser Absorption Spectrom...

متن کاملAnalysis of Range Measurements From a Pulsed Airborne CO2 Integrated Path Differential Absorption Lidar
Determining the CO2 column abundance from an integrated path differential absorption (IPDA) lidar requires accurate knowledge of the range to the scattering surface, i.e., the column height. We have adapted and tested a ranging algorithm for the airborne IPDA CO2 lidar designed at the NASA Goddard Space Flight Center, and have evaluated its accuracy and precision. We applied a quasi-maximum-lik...
