North America Snow Cover Maps

This entry contains Snow Cover Maps for Norh America with statelines, using the MODIS Cloud-gap-filled (CGF) Product at ~25-km resolution. The MODIS CGF product seeks to provide clear snow observations by filling cloudy areas on a given day with clear observations from previous days.The usual source for this product is the MOD10C1 MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG, Version 5 and a variant has been coded that can use MOD10A1 MODIS/Aqua Snow Cover Daily L3 Global 500m Grid, Version 5 as source.

Maps are provided for various dates for 2006, 2010, 2011 and 2012, to compare snow cover between years.
