REMOTE SENSING SYSTEMS
The ASF operates a suite of facility instruments that are used for Earth Science process studies, satellite calibration and validation, and algorithm development. The data are used by a variety of multi-disciplinary science programs to monitor variation in environmental conditions, assess global change, and respond to natural disasters.
All of the data are made available to the public free of charge through various NASA data archives, as noted in the individual sections below. New data acquisitions for ESD-funded researchers, and others, may be requested through the NASA Flight Request System.
