European Drought Observatory
The EDO pages contain drought-relevant information such as maps of indicators derived from different data sources (e.g., precipitation measurements, satellite measurements, modelled soil moisture content). Different tools, like Graphs and Compare Layers, allow for displaying and analysing the information and irregularly published "Drought News" give an overview of the situation in case of imminent droughts.
