The LAADS DAAC, whose discipline domain is atmospheric science, serves the global science research and applications communities by providing efficient access to science data products, services, tools, and all related resources for the NASA Terra and Aqua MODIS (Moderate resolution Imaging Spectroradiometer), and SNPP (Suomi-National Polar-orbiting Partnership) VIIRS (Visible Infrared Imaging Radiometer Suite) Level 1 and atmosphere data sets. LAADS is collocated with two NASA Science Investigator-led Processing System (SIPS), the MODIS Adaptive Processing System (MODAPS) and the VIIRS Level 1 and Land SIPS. These SIPS are responsible for producing all levels of both NASA Terra and Aqua MODIS science data products, and of NASA standard versions of the NPP Suomi VIIRS science products. LAADS also hosts ESA’s (European Space Agency) Envisat MERIS and Sentinel-3 SLSTR and OLCI product collections, in addition to related airborne data that include related airborne data collections.
