Summary
Abstract:
MODIS/Aqua Snow Cover 8-Day L3 Global 500m Grid (MYD10A2) contains data fields for maximum snow cover extent over an eight-day compositing period and a chronology of snow occurrence observations in HDF-EOS format, along with corresponding metadata. MYD10A2 consists of 1200 km by 1200 km tiles of 500 m resolution data gridded in a sinusoidal map projection. Data extend from 04 July 2002 to present. ... MODIS snow cover data are based on a snow mapping algorithm that employs a Normalized Difference Snow Index (NDSI) and other criteria tests. The only data available for Version 4 (V004) is the Golden Month, which is a sample of V004 data covering the time period 29 August 2002 (day of year 241) through 7 October 2002 (day of year 280). The Golden Month is only available by special request by contacting NSIDC User Services. Please note that NSIDC now has a complete series of Version 5 data, which is the highest version number now available and represents the best quality of data.

Quality
Quality indicators for MODIS snow data are represented by 'AutomaticQualityFlag' and 'ScienceQualityFlag' metadata objects, and their corresponding explanations ('AutomaticQualityFlagExplanation' and 'ScienceQualityFlagExplanation') in the CoreMetadata.0 global attribute; and also in the 'Snow Cover PixelQA' data field. These are generated during production or in post-product scientific and quality checks of the data product.
