Sentinel-2 Snow Cover Extent (SCE) for LammiLTER e-shape site of years 2019 and 2020.

Details on methodology used can be found in this reference: https://doi.org/10.3390/rs13101957.

The final output consists of 20 m resolution raster masks in GeoTIFF format with: 0, No snow; 100, Snow; 205, Cloud; 254, No Data.

The SCE maps were validated against in situ data collected by weather stations equipped with snow gauges. The following metrics were computed: the class metrics Producer Accuracy (PA), User Accuracy (UA) and F1-score (F1) and the overall metrics Overall Accuracy (OA) and Macro-F1-score:

OA 0.910 Snow PA 0.882 Snow UA 0.750 Snow F1 0.811 No-Snow PA 0.918 No-Snow UA 0.966 No-Snow F1 0.941 Macro-F1 0.876
