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...
