Abstract
This paper presents data sets derived from MODIS imagery related to snow cover extent and phenology (duration, start and end of the season). The data are based on yearly information and can provide support for understanding the related changes in the last 23 years, and in correlation with changes in water resources and/or vegetation. The data set contains yearly averaged snow cover fraction (SCF), snow cover duration (SCD), first snow day (FSD) and last snow day (LSD).
