Space-based Information: | The Database for Hydrological Time Series of Inland Waters (DAHITI) was developed by the Deutsches Geodätisches Forschungsinstitut der Technischen Universität München (DGFI-TUM) in 2013. DAHITI provides water level time series of lakes, reservoirs, rivers, and wetlands derived from multi-mission satellite altimetry for hydrological applications. All water level time series are free available for the user community after a short registration process. Altimeter Data For the estimation of water heights, multi-mission altimeter data are used. In detail, altimeter missions such as Topex (NASA, CNES), Jason-1 (NASA, CNES), Jason-2 (NASA, CNES, NOAA, EUMETSAT ), Jason-3 (NASA, CNES, NOAA, EUMETSAT ), GFO (US Navy), Envisat (ESA), ERS-1 (ESA), ERS-2 (ESA), Cryosat-2 (ESA), IceSAT (NASA), SARAL/AltiKa (ISRO, CNES) and Sentinel-3A (ESA) are used. |
