MODIS/Terra Snow Cover 5-Min L2 Swath 500m, Version 6
Data set id:
MOD10_L2
DOI: 10.5067/MODIS/MOD10_L2.006
There is a more recent version of these data.
Version Summary
Changes for Version 6 include:

  • Fractional Snow Cover has been replaced by Normalized Difference Snow Index (NDSI) snow cover. Fractional Snow Cover is no longer calculated;

  • The binary Snow-Covered Area (SCA) map has been discontinued;

  • Data screens designed to reduce snow detection errors have been revised and several new screens have been added;

  • Data screen results, including snow detection reversals and detections with increased uncertainty, are provided in a new QA bit flag;

  • Basic pixel-level QA uses new criteria to indicate the overall quality of algorithm result.

Overview

This data set reports the location of snow cover based on the 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 Terra satellite. As of August 2023, this data set is retired and no longer available for download. We recommend using MODIS/Terra Snow Cover 5-Min L2 Swath 500m, Version 61 as an alternative.

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
