Statement

Created from MODIS daily snow cover products MOD10A1, MYD10A1 provided by the National Snow and Ice Datacenter NSIDC ( https://nsidc.org/)

Processing steps include combination of observations recorded by Aqua and Terra, temporal interpolation of 3 successive days, snow line identification, and a seasonal filter. More details are available in the publication "Dietz A.J., Kuenzer, C., and Dech, S. (2015): Global SnowPack: a new set of snow cover parameters for studying status and dynamics of the planetary snow cover extent; Remote Sensing Letters 6, No. 11. pp. 844-853

Description

Single day snow cover datasets MOD10A1 and MYD10A1 were first cleared of any clouds/data gaps/polar darkness areas using 4 different interpolation techniques, then merged to produce the seasonal products.

Accuracy of the seasonal product ranges between 77% and 85%, depending on the location and the duration of data gaps caused by clouds or darkness.
