Abstract

Snow Cover Duration (SCD), First Snow Day (FSD), Last Snow Day (LSD) extracted from Sentinel-2 time series of years 2019 and 2020. The snow year is considered from the 1st September to 31st August of the following year. The snow season is considered continuous if at least 14 consecutive days of snow are detected. FSD: first day of a continuous snow season LSD: last day of a continuous snow season SCD: days between FSD and LSD of the same snow year (days)

Description - Methods

Detection methodology used will be soon accessible

Description - TechnicalInfo

The final output consists of 20 m resolution raster layers in GeoTIFF format with the following values per pixel: FSD = first day of a continuous snow season, expressed as Day Of the Snow Year (DOYS) LSD = last day of a continuous snow season, expressed as Day Of the Snow Year (DOYS) SCD = number of days of continuous snow cover The SCD maps were validated against in situ data collected by weather stations equipped with snow gauges. The following metrics were computed: Root Mean Squared Error (RMSE), Mean Absolute Error (MAE) and Mean Bias Error (MBE). RMSE = 16.5 days MAE = 14 days MBE = 6.5 days
