PATMOS-x (Pathfinder Atmospheres - Extended) was developed at NOAA/NESDIS/STAR in collaboration with the University of Wisconsin - Madison CIMSS (Cooperative Institute for Meteorological Satellite Studies). PATMOS-x builds upon the original PATMOS project, which was one of the original NASA/NOAA Pathfinder Projects. The PATMOS-x cloud algorithms were created by leveraging development performed for the GOES-R and JPSS programs as well as operational processing at NOAA/NESDIS.
