The Active Sensing of CO2 Emissions over Nights, Days, and Seasons (ASCENDS) CarbonHawk Experiment Simulator (ACES) is a NASA Langley Research Center instrument funded by NASA’s Science Mission Directorate that seeks to advance technologies critical to measuring atmospheric column carbon dioxide (CO2) mixing ratios in support of the NASA ASCENDS mission. The ACES instrument, an Intensity-Modulated Continuous-Wave (IM-CW) lidar, was designed for high-altitude aircraft operations and can be directly applied to space instrumentation to meet the ASCENDS mission requirements. The ACES design demonstrates advanced technologies critical for developing an airborne simulator and spaceborne instrument with lower platform consumption of size, mass, and power, and with improved performance.

ACES recently flew on the NASA DC-8 aircraft during the 2017 ABoVE/ASCENDS airborne measurement campaign to test ASCENDS-related technologies in the challenging Arctic environment. ACES and the NASA Goddard CO2 Sounder collected the first Integrated Path Differential Absorption (IPDA) lidar measurements in the Arctic. Data were collected over a wide variety of surface reflectivities, terrain, and atmospheric conditions during the campaign’s 8 research flights (over 55 hours of science data). Simultaneous data were collected by in situ instrumentation on the aircraft.
