Snowpack indicator only applies in those regions where snowpack accumulation is regular annually. These regions in the EU are mainly the Nordic countries, the Alps, the Pyrenees and the Carpathian Mountains. Nevertheless, the impact of snowpack to the hydrology is not limited only to these regions. Several large Central Europe rivers’ flow, e.g. the Rhein, partly depends on the melting snowpack of the Alps

Data requirements to use: None;

Data used: European Space Agency's (ESA) GlobSnow project led by the Finnish Meteorological Institute (FMI) has developed and provides snowpack water equivalent (SWE) values for the whole Northern Hemisphere. The SWE data is based on passive microwave radiometer data combined with ground-based synoptic snow observations. The SSPI is calculated based on SWE values by the FMI for the whole EU.;

Data format: N/A;

Data access: website;

Concise description:

The SSPI is computed the same way as the SPI (Standardized Precipitation Index), except for being based on the daily snowpack water equivalent (=kg/m2 of snow) time series. The SSPI provides information of the relative volume of the snowpack in the catchment on a ten-daily and monthly basis compared to the period of reference. The indicator can be used for awareness raising, evaluation of occurred droughts, forecasting future drought risks and management purposes.
