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 1-month Standardized Precipitation Index (SPI-1) is an indicator used to monitor meteorological drought based on precipitation anomalies over 1-month accumulation periods. SPI-1 serves as a proxy indicator for immediate impacts of droughts such as reduced ...

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...

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 6-month Standardized Precipitation Index (SPI-6) is a meteorological drought indicator to monitor precipitation anomalies over 6-month accumulation periods and is a proxy indicator for medium-term impacts, for example reduced stream flow and reservoir stor...

The 12-month Standardized Precipitation Index (SPI-12) is a meteorological drought indicator to monitor precipitation anomalies over 12-month accumulation periods and is a proxy indicator for medium-term impacts, for example reduced stream flow and reservoir s...

The 9-month Standardized Precipitation Index (SPI-9) is a meteorological drought indicator to monitor precipitation anomalies over 9-month accumulation periods and is a proxy indicator for medium-term impacts, for example reduced stream flow and reservoir stor...

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...

This indicator outlines persistent anomaly conditions of low precipitation, as discrete events in space and time, at the global scale and at near real-time, every ten days. By providing information on the duration and spatial extent of droughts, it allows for ...

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...

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 ...

Combined Drought Indicator 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 recovery process to normal conditions after a ...

Average root zone Soil Moisture Index (SMI) at 5-km spatial resolution. The dataset is derived from 6-hourly LISFLOOD modelled soil moisture in the top two soil layers, as produced for EFAS on a Lambert Azimuthal Equal Area projection.

Soil Moisture Anomaly (SMA) at 5-km spatial resolution, computed as standardized deviation from a baseline period 1995-2020. The dataset is derived from 6-hourly LISFLOOD modelled soil moisture in the top two soil layers, as produced for EFAS on a Lambert Azim...
