Sentences with phrase «scatterometer winds»

The OSI SAF team focuses on scatterometer winds (and soon microwave winds), Sea Surface Temperature (SST) and sea Ice Surface Temperature (IST), radiative fluxes: Solar Surface Irradiance (SSI) and Downward Longwave Irradiance (DLI), sea ice concentration, edge, type, emissivity, drift.

You can find material on scatterometer winds products and software and their use on the Scatterometry Training page.

Bentamy A., Y. Quilfen, and P. Flament, 2002: Scatterometer wind fields - a new release over the decade 1991?

2DVAR performs an incremental analysis based on the ambiguous scatterometer wind vector solutions and a model forecast, and selects the most likely solution.

Not exact matches

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 scatterometer provides 15 times more information about the wind than ships in the northern hemisphere and 100 times more in the southern hemisphere.

The improved predictions are largely due to one particular instrument aboard ERS - 1, the microwave scatterometer, which deduces the speed of the wind at sea level by measuring the roughness of the sea's surface.

The other Airbus - built instrument, the «Advanced Scatterometer» (ASCAT) is an active radar instrument which measures wind speed and direction over the open sea.

The remotely sensed winds and latent heat fluxes are mainly derived from the scatterometers onboard the European Remote Sensing Satellites (ERS - 1 and ERS - 2), NASA scatterometer (NSCAT) onboard ADEOS - 1, Seawinds scatterometer onboard QuikSCAT, and from the radiometers onboard the Defense Meteorological Satellite Program (F10, F11, F13, F14, and F15).

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.

This new product available at CERSAT consists of weekly and monthly gridded fields of CO2 exchange coefficients derived from scatterometer ocean surface winds and sea surface temperature, using severa...

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.

The synergy of an active scatterometer and a passive radiometer on the same platform is significant and would improve both the scatterometer vector wind retrievals and the radiometer SST retrievals.

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.
