Liu, W. T., X. Xie, and W. Tang, 2010: Scatterometer's unique capability in measuring ocean surface stress.

The European Remote - Sensing Satellites (ERS - 1 and ERS - 2), launched by the European Space Agency respectively on July 17, 1991 and April 21, 1995, carry the first satellite - borne C - band (5.3 GHz) Active Microwave Instrument (AMI) capable of measuring, in scatterometer mode, surface wind speeds and directions over the oceans.

New gridded daily wind fields from Metop / ASCAT scatterometer retrievals are produced in near real - time over global ocean with a spatial resolution of 0.25 °.

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 main improvements with respect to V2 version flux products (Bentamy et al, 2008) are related to the improvements of the specific air humidity estimation from radiometer measurements, to the assessment of the surface winds retrieved from QuikSCAT scatterometers, and to the use of the new objective method allowing the calculation of flux analyses over the global oceans.

Both consist of a dedicated free - flyer scatterometer mission at the nearest possible opportunity in order to avoid, or at least minimize, a gap in the ocean surface vector winds CDR.

Tested on airborne missions this spring, DopplerScatt is a cousin of QuickSCAT and RapidScat, which used a scatterometer to measure the «roughness» of the ocean surface and determine the direction and intensity of wind.

Neither of these scatterometers can therefore be considered viable mitigation strategies for continuation of the ocean surface vector winds CDR.

QuikSCAT measurements are also limited to a spatial resolution of 12.5 km and are not routinely made closer than about 30 km from land.26 Many in the microwave breakout group argued that high priority should be given to a sustained, more capable, next - generation scatterometer program that can meet these requirements while at the same time continuing the ocean surface vector winds CDR established by QuikSCAT.
