MODIS/Terra Sea Ice Extent and IST Daily L3 Global 4km EASE-Grid Day (MOD29E1D) contains the following fields: sea ice by reflectance and ice surface temperature (IST). Each data granule covers the entire globe with two separate arrays of 4321 x 4321 pixels: one for the Arctic and one for the Antarctic. Data extend from 15 September 2003 to present. Version 4 (V004) is the latest version of MODIS data available from NSIDC. 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. Data are available by FTP, CD-ROM, DVD, or DLT.

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.
