This is the most recent version of these data.
Version Summary
Version Summary
The low visible reflectance screen for snow cover using bands 2 and 4 was lowered from 0.10 to 0.07 and cloud mask algorithm flags are set for 'probably cloudy' and 'probably clear' sky conditions.
Overview
This global Level-2 (L2) data set provides daily snow cover detected using Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections. The NDSI is derived from radiance data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Aqua satellite: DOI:10.5067/MODIS/MYD02HKM.061 and DOI:10.5067/MODIS/MYD021KM.061. Each data granule contains 5 minutes of swath data observed at a resolution of 500 m.
The terms "Version 61" and "Collection 6.1" are used interchangeably in reference to this release of MODIS data.

General Questions & FAQs
For the snow cover and sea ice products, users can use MODIS Collections 6 and 6.1 together.
Data products from VIIRS are created to be similar to MODIS data products to ensure the continuity needed for the development of snow and sea ice climate records beyond the life expectancy of MODIS. The temporal resolution and spatial extent are identical in MODIS and VIIRS.
The lag time between observations and availability of MODIS products is only a few days. Lag time may be extended due to satellite maneuvers and extra quality assurance required for the geolocation data after the maneuver.

The Normalized Difference Snow Index (NDSI) snow cover is an index that is related to the presence of snow in a pixel and is a more accurate description of snow detection as compared to Fractional Snow Cover (FSC). Snow typically has very high visible (VIS) reflectance and very low reflectan
