MODIS/Terra Sea Ice Extent Daily L3 Global 1km EASE-Grid Day (MOD29P1D) data set contains fields for Sea Ice by Reflectance, Sea Ice by Reflectance Spatial QA, Ice Surface Temperature (IST), and Ice Surface Temperature Spatial QA in Hierarchical Data Format-Earth Observing System (HDF-EOS) format, along with corresponding metadata. The fields Sea Ice by IST and Combined Sea Ice that were in Version 4 were removed from Version 5. MOD29P1D Version 5 (V005), the latest version of the Moderate Resolution Imaging Spectroradiometer (MODIS) data, consists of 954 x 954 km files of 1 km resolution data gridded in the Lambert Azimuth Equal Area map projection. 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. MODIS/Terra 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 NSIDC User Services at http:// nsidc.org/forms/contact.html.
