Sentences with phrase «microwave scatterometer»
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 storm - chasing aircraft's new scatterometer — a microwave radar sensor that measures the reflection (or scattering effect) produced while scanning the surface of the Earth — can see inside the storm with high resolution, something akin to a magnetic resonance imaging (MRI) scan.
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).
Improve sea ice classification based on Synthetic Aperture Radar (SAR), scatterometers and passive microwave (PMW) sensors.
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.
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.
For several years the CERSAT has been providing sea ice maps derived from various scatterometers (microwave radar) on board earth observation satellites (ERS - 1, ERS - 2, ADEOS - 1 or QuikSCAT).
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.
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.
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.
