MODIS/Terra Snow Cover Daily L3 Global 500m Grid, Version 61

This data set contains daily, gridded snow cover and albedo derived from radiance data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Terra satellite. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections.

Version Summary:

The low visible screen in the algorithm was changed and two new bit flags are set in the QA, content of local attributes were revised but no attribute name changes or additions.
