MODIS/Terra Sea Ice Extent and IST Daily L3 Global 4km EASE-Grid Day (MOD29E1D) data set contains fields for sea ice by reflectance and Ice Surface Temperature (IST). Each data granule covers the entire globe with two separate arrays of 4501 x 4501 pixels: one for the Arctic and one for the Antarctic. The MODIS 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. MODIS/Terra Version 5 (V005) data extend from 24 February 2000 to present; however, until reprocessing is complete in mid-2008 not all V005 data will be available. Data are available by FTP, CD-ROM, DVD, or DLT. Data can be obtained in GeoTIFF format by ordering the data through the Data Pool.

Until the reprocessing campaign is finished, the complete set of Version 4 (V004) data will remain available. Thus, if you need V004 documentation, please contact the National Snow and Ice Data Center (NSIDC) User Services at http://nsidc.org/forms/contact.html.
