Data requirements to use: None;
Data used: The GPCC and the ECMWF atmospheric reanalysis ERA-Interim precipitation datasets are used as the main sources of precipitation. ERA-Interim monthly temperature and soil moisture including their anomalies are also displayed. The vegetation conditions are assessed through the anomaly of fAPAR (fraction of Absorbed Photosynthetically Active Radiation; Gobron et al., 2007) 10-day time composite derived from the
Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. The meteorological seasonal forecast relies in the ECMWF dynamical ocean-atmosphere coupled system 4 (S4);

Concise description:
The main monitoring products are the precipitation and their derived indicators, such as the precipitation anomalies (% of normal) and the Standardized Precipitation Index (SPI). Drought vulnerability and risk are assessed at country and basin level following a socio-economic approach (Naumann et al., 2013b). Regarding the seasonal forecast, the two main outputs are the forecasted SPI following a probabilistic or a deterministic approach. A number of geographic background data sets are also available such as climate classifications (Aridity Index and Köppen-Geiger Classification), land cover and soil maps (Land cover, Agricultural Management Factor, Soil Fertility Index), water resources (Irrigation cropping pattern zones, Surface water bodies and River Basins), and population indicators (Population Density and Infant Mortality Rate)
Indices included:
Precipitation and derived indicators, such as the precipitation anomalies (% of normal) and the Standardized Precipitation Index (SPI), Vegetation productivity anomaly, drought hazard index, drought vulnerability index, drought risk
