MODIS/Terra Sea Ice Extent 5-Min L2 Swath 1km NRT

Published by NASA/GSFC/EOS/ESDIS/LANCE MODIS | National Aeronautics and Space Administration | Catalog Last Checked: June 23, 2026 at 08:38 PM | Dataset Last Updated: June 23, 2026
MODIS/Terra Sea Ice Extent 5-Min L2 Swath 1km Near Real Time (NRT), short name MOD29, contains the following fields: sea ice by reflectance, sea ice by reflectance pixel quality assurance (QA), ice surface temperature (IST), IST pixel QA, sea ice by IST, combined sea ice, latitudes, and longitudes in HDF-EOS format, along with corresponding metadata. Latitude and longitude geolocation fields are at 5 km resolution, while all other fields are at 1 km resolution. The sea ice algorithm uses a Normalized Difference Snow Index (NDSI) modified for sea ice to distinguish sea ice from open ocean, based on reflective and thermal characteristics.
