Description

This global Level-2 (L2) product provides daily sea ice extent and ice surface temperature. The data are derived from Level-1B radiances acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Terra satellite. Each data granule contains 5 minutes of swath data observed at a resolution of 1000 m.

The terms "Version 61" and "Collection 6.1" are used interchangeably in reference to this release of MODIS data.

Version Description

The C61 science algorithm is the same as the C6 algorithm. Any improvement to the C61 product compared to the C6 product comes from enhancements to the calibration approach used to generate the input products and from updates to the polarization correction used in C61 reprocessing.
