SUCCESS: SUbsonic aircraft: Contrail & Cloud Effects Special Study (SUCCESS)


SUCCESS is a NASA field program using scientifically instrumented aircraft and ground based measurements to investigate the effects of subsonic aircraft on contrails, cirrus clouds and atmospheric chemistry. The experiment is cosponsored by NASA's Subsonic Assessment Program and the Radiation Sciences Program which are part of the overall Aeronautics and Mission to Planet Earth Programs, respectively. SUCCESS has well over a hundred direct participants from several NASA Centers, other agencies, universities and private research companies. SUCCESS is coordinating with the Department of Energy's Atmospheric Radiation Measurements Program (ARM) which operates the Clouds and Radiation Testbed (CART) site located in Northern Oklahoma, and Southern Kansas. In addition to the extensive ground based measurements at the CART site, ARM will also make airborne measurements with scientifically instrumented Remotely Piloted Aircraft (RPA's). SUCCESS has several objectives. We plan to better determine the radiative properties of cirrus clouds and of contrails so that satellite observations can better determine their impact on Earth's radiation budget. We hope to determine how cirrus clouds form, whether the exhaust from subsonic aircraft presently affects the formation of cirrus clouds, and if the exhaust does affect the clouds whether the changes induced are of climatological significance. We seek to pave the way for future studies by developing and testing several new instruments. We also plan to better determine the characteristics of gaseous and particulate exhaust products from subsonic aircraft and their evolution in the region near the aircraft.
