Description:

Abstract:: Sea ice products from the Moderate Resolution Imaging Spectroradiometer (MODIS) include level 2 swath data and level 3 gridded day and night composites, at 1 km resolution. Level 3 products consist of tiles of data, approximately 1200 km by 1200 km in area, gridded in a Lambert Azimuthal Equal-Area (EASE-Grid) projection. The sea ice algorithm uses a Normalized Difference Sea Ice Index (NDSI) and other criteria to distinguish sea ice from open ocean, based on reflective characteristics. The level 2 swath product (MOD291) contains the following fields: Sea Ice by Reflective Characteristics, Sea Ice by Reflective Pixel Quality Assurance (QA), Ice Surface Temperature (IST), IST Pixel QA, Sea Ice by IST, Combined Sea Ice, Latitude, and Longitude. The data also contain local and global metadata. Latitude and longitude geolocation fields are at 5 km resolution, while all other fields are at 1 km resolution. Sea ice data are in HDF-EOS format and are available by ftp. MODIS sea ice products are considered provisional at this time. Product quality may not be optimal, and incremental product improvements are still occurring.
