Instrument:
MODIS

Product Description:
MODIS Near Real Time (NRT) Sea Ice Extent 5-Min L2 Swath 1km, MYD29, data set contains fields for sea ice by reflectance, sea ice by reflectance pixel Quality Assessment (QA), Ice Surface Temperature (IST), IST pixel QA, latitudes and longitudes in Hierarchical Data Format Earth Observing System (HDF-EOS) format along with corresponding metadata. Latitude and longitude geolocation fields are at 5km resolution while all other fields are at 1km 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.
