OVERCAST
Global, multisensor 3D cloud analysis in near real-time
OVERCAST aims to provide an accurate estimate of time-resolved 3D cloud structures using global operational satellites, combined with a number of ancillary products, provided in near real-time. Please see the Science and Applications tab above for a description of our products.
The project is sponsored by the US Office of Naval Research (ONR) and supports basic research, with additional civilian applications. The Cooperative Institute for Research in the Atmosphere (CIRA) partners include the Naval Research Lab (NRL) and the Cooperative Institute for Meteorological Satellite Studies (CIMMS).
