Heat- or coldwaves are classified by duration in days starting from more than one day. The present-day heat/cold wave is classified by accumulating all the past consecutive days with heat/cold wave until the present-day. However, for any past date the duration...

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 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 1-month Standardized Precipitation Index (SPI-1) is a meteorological drought indicator to monitor precipitation anomalies over 1-month accumulation periods and is a proxy indicator for immediate impacts of droughts such as reduced soil moisture, snowpack, ...

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 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 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 streamflow 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 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 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 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 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 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...
