As part of NASA’s Earth Science enterprise, the AIRSAR data are currently collected for NASA-funded investigators in the United States as well as sponsors from international organizations. Calls for flight request are made on a yearly basis from NASA Headquarters, where the flight requests are also approved. Once the flight season is scheduled, JPL works with the selected investigators to optimize data collection. Following data collection, data are processed at JPL and then delivered to the customers. All processed data are archived and catalogued at JPL.
