Continuous
scatterometer data series exist since 1991 and are processed into climate data records, providing links to the ESA CCI or ERA - CLIM.
Algorithms to process the three - beam
scatterometer data have been developed at Institut Franais de Recherche pour l'Exploitation de la Mer (IFREMER).

Raw
data collected from altimeters have been re-processed and collated with wind speed
data from
scatterometers and sea level measurements from tide gauges, to show the spatial structure of each storm.
The latest results show that in the northern hemisphere and the tropics, the
data from the
scatterometer makes no difference to the accuracy of the weather forecasts.
The satellite
data come from the European Remote Sensing satellite
scatterometers (ERS - 1 and ERS - 2), NASA
scatterometers (NSCAT and Seawinds onboard ADEOS - 1 and QuikScat respectively), and several defense Meteorological Satellite Program (DMSP) radiometers (Special Sensor Microwave / Imager [SSM / I] F10 - F15).
The team then extrapolated these
data over the varying landscape to produce a seamless map, using NASA imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASA's Terra spacecraft, the QuikScat
scatterometer satellite and the Shuttle Radar Topography Mission.
The researchers compared the GNSS - R satellite measurements with
data from other sources, including tropical cyclone best track
data from the National Oceanic and Atmospheric Administration's National Centers for Environmental Information; two climate reanalysis products; and a spaceborne
scatterometer, a tool that uses microwave radar to measure winds near the surface of the ocean.
The SeaWinds on QuikSCAT mission is a «quick recovery» mission to fill the gap created by the loss of
data from the NASA
Scatterometer (NSCAT), when the satellite it was flying on lost power in June 1997.
With MIS delayed until NPOESS C2, there is a need to continue the long (28 - year) climate
data record of sea ice extent and concentration collected by passive microwave radiometers; continued
scatterometer and altimeter measurements are also required.
