Datasets

The dataset provides global annual glacier mass changes distributed on a global regular grid at 0.5° resolution (latitude, longitude) based on the Fluctuations of Glaciers (FoG) database of the World Glacier Monitoring Service (WGMS). Glaciers play a fundamental role in the Earth’s water cycles. They are one of the most important freshwater resources for societies and ecosystems and the recent increase in ice melt contributes directly to the rise of ocean levels.

This dataset, commonly known as the Randolph Glacier Inventory (RGI), provides global glacier outlines compiled from maps, aerial photographs and satellite images. The dataset is a snapshot (one outline per glacier) constructed from source data that were mostly acquired in the period 1998-2010.

This dataset provides daily estimates of snow-covered land areas obtained from observations collected by multiple optical satellite instruments. As snow cover plays a crucial role in weather and climate, this data is particularly valuable for monitoring, estimating and assessing relevant changes.
It provides Level 3 collated (L3C) processed products, namely global daily single-sensor Snow cover fraction viewable (SCFV) and Snow cover fraction on ground (SCFG) products, both of which are based on optical satellite data.
