MODIS/Terra Near Real Time (NRT) Sea Ice Extent 5-Min L2 Swath 1km
Listed in NASA Data Portal
Description
MODIS/Terra Near Real Time (NRT) Sea Ice Extent 5-Min L2 Swath 1km (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.
Version 4 (V004) is the latest version of MOD29 data available. MODIS/Terra V004 data extend from 24 February 2000 to present. 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.

The only data available for Version 4 (V004) is the Golden Month, which is a sample of V004 data covering the time period 29 August 2002 (day of year 241) through 7 October 2002 (day of year 280). The Golden Month is only available by special request by contacting NSIDC User Services. Please note that NSIDC now has a complete series of Version 5 data, which is the highest version number now available and represents the best quality of data.
