Description

Aeolus-CalVal-HALO_DC8_1 is the Aeolus CalVal HALO Aerosol and Water Vapor Profiles and Images data product. Data was collected using the High Altitude Lidar Observatory (HALO) instrument on the Douglas (DC-8) Aircraft. Data collection for this product is complete.

NASA conducted an airborne campaign from 17 April to 30 April 2019 to: 1) demonstrate the performance of the Doppler Aerosol WiNd Lidar (DAWN) and High Altitude Lidar Observatory (HALO) instruments across a range of aerosol, cloud, and weather conditions; 2) compare these measurements with the European Space Agency Aeolus mission to gain an initial perspective of Aeolus performance in preparation for a future

international Aeolus Cal/Val airborne campaign; and 3) demonstrate how weather processes can be resolved and better understood through simultaneous airborne wind, water vapor (WV), and aerosol profile observations, coupled with numerical model and other remote sensing observations. Five NASA DC-8 aircraft flights, comprising 46 flight hours, were conducted over the Eastern Pacific and Southwest U.S., based out of NASA Armstrong Flight Research Center in Palmdale, CA and Kona, HI. Yankee Environmental Systems, Inc High Definition Sounding System (HDSS) eXpendable Digitial Dropsondes (XDD) were used to validate the DAWN and Aeolus wind observations. The LaRC Diode Laser Hygrometer instrument, which was integrated on the DC-8 in preparation for another NASA airborne campaign, provided in-situ WV measurements used during one flight to validate HALO and dropsonde WV profile products.
