Sentences with phrase «from scatterometers»

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).

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.

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...

The one drawback of the scatterometer is that it can not distinguish between a breeze from one quarter and one blowing from the opposite direction.

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.

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 °.

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.

NASA's Quick Scatterometer (QuikSCAT) was lofted into space at 7:15 p.m. Pacific Daylight Time on Saturday (6/19/99) atop a U.S. Air Force Titan II launch vehicle from Space Launch Complex 4 West at California's Vandenberg Air Force Base.

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 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.

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.
