Quality This is a near real-time (NRT) product that has undergone expedited processing to make it available within 3 hours of observation time to meet the needs of the NRT applications community. NRT data are subject to geolocation errors or reprocessing. Usually the geolocationalerrors are minimal (less than 100 meters), however, there are situations, particularly before and after spacecraft maneuvers and during space weather events, when the difference can increase up to several kilometers.
Access Constraints No constraints but users need to be registered with the ESDIS User Registration system (https://urs.eosdis.nasa.gov/users/new) to download files via the FTP site.
