The GAUSS project supports the Finnish Environment Institute (SYKE) in the provision of a new hydrological drought index based on satellite data.
SYKE supports Statistics Finland by providing hydrological measurements across the country, based on a network of 1690 in-situ stations. In this case study we complement these data points by virtual tide gauges, based on satellite altimeter data from Sentinel 3 and other spacecraft. These are taken together with in situ water gauges to measure river and lake heights across a wide region, and are then combined to produce a quantifiable hydrological drought index.
Use case-specific infographics have been developed to illustrate the project’s outcomes:
