The 24-month Standardized Precipitation Index (SPI-24) is a meteorological drought indicator to monitor precipitation anomalies over 24-month accumulation periods and is a proxy indicator for long-term impacts, for example, reduced reservoir and groundwater re...

The 48-month Standardized Precipitation Index (SPI-48) is a meteorological drought indicator to monitor precipitation anomalies over 48-month accumulation periods and is a proxy indicator for long-term impacts, for example, reduced reservoir and groundwater re...

The Risk of Drought Impacts for Agriculture (RDrI-Agri) indicator that is implemented in the Global Drought Observatory (GDO) of the Copernicus Emergency Management Service, is used for determining the area more likely to be affected by droughts. Higher risk m...

The LFI indicator exploits the simulated 6-hours river water discharge outputs of the JRC’s in-house LISFLOOD hydrological model, in order to capture unbroken consecutive periods of unusually low streamflow, and compares the consequent water deficit during tho...

The FAPAR Anomaly indicator that is implemented in the Copernicus Global Drought Observatory (GDO) is used to detect and monitor the impacts on vegetation growth and productivity of environmental stress factors, especially plant water stress due to drought. Th...

The FAPAR indicator used in the Copernicus Global Drought Observatory (GDO) is the satellite-measured biophysical variable Fraction of Absorbed Photosynthetically Active Radiation (FAPAR, sometimes written as fAPAR or FPAR), composited for 10-day intervals, fr...

Soil moisture anomaly maps are computed on a 30-day moving window at a spatial resolution of 0.1 decimal degrees and updated every 10 days. Moving windows have an ordinal reference: - 1st window of month M goes from day 11 of month M-1 to day 10 of month M (e....

The Crop Masks used in the European Drought Observatory (EDO) and Global Drought Observatory (GDO) consist of 36 binary spatial layers (one for each 10-day period of the year) used to depict the location and extent of crop in its growing season. The input data...

The FAPAR indicator used in the Copernicus Europeran Drought Observatory (EDO) is the satellite-measured biophysical variable Fraction of Absorbed Photosynthetically Active Radiation (FAPAR, sometimes written as fAPAR or FPAR), composited for 10-day intervals,...

The 3-month Standardized Precipitation Index (SPI-3) is a meteorological drought indicator to monitor precipitation anomalies over 3-month accumulation periods and is a proxy indicator for immediate impacts of droughts, such as reduced soil moisture, snowpack,...

The Snow Masks used in the European Drought Observatory (EDO) are a collection of time-varying binary spatial layers (one for each 10-day period of the year) used to depict the location and extent of snow on the ground. The input data for calculating the snow...

Combined Drought Indicator (CDI) based on SPI, soil moisture and fAPAR, to identify areas with potential to suffer agricultural drought, areas where the vegetation is already affected by drought conditions, and areas in the recovery process to normal condition...

The CDI is used to identify areas suffering from various degrees of drought (areas at risk of agricultural drought, areas where the vegetation has already been affected and areas recovering from drought) and their spatial extent. As the name suggests, the CDI ...

Activation date: 2023-12-21 Event type: Flood Activation reason: In the wake of Storm Ciarán's destructive path across Western Europe from late October to early November 2023, the region of Tuscany in central Italy faced catastrophic flood...
