Pre SWOT Hydrology GRRATS Daily River Heights and Storage Version 2
The Global River Radar Altimeter Time Series (GRRATS) 1km/daily interpolations are river heights from ERS-1, ERS-2, TOPEX/Poseidon OSTM/Jason-2 and Envisat that are interpolated and processed to create a continuous heights for the study over the temporal range of the altimeters used. The purpose of these heights are to provide satellite altimetric river height data in a form that is more recognizable to the observational community and as a way to get users use to using satellite data for river hydrology. These pre SWOT data are derived from satellites to provide hydrological measurements. The Surface Water and Ocean Topography (SWOT) mission will have hydrology as one of its objectives. This dataset does not have the same variables as SWOT, but does provide hydrological measurements with typical quality flagging typical of satellite data. Not only does it provide science information, it can also assist hydrological users new to satellite data with the satellite data formats and variables before SWOT launches.
