WebThe SeaWinds scatterometer is a specialized microwave instrument that measures near-surface wind speed and direction all the time, even when it is cloudy. Although designed for measurements over the ocean, SeaWinds can also collect data over land and ice. In a continuous 1,800-kilometer-wide band, Sea Winds makes approximately 400,000 ... Web1 Introduction. Sea surface wind field is important for marine monitoring, numerical weather prediction as well as other marine and atmospheric science studies and becomes a focus in the research fields of meteorology and oceanography (Stewart, 2008).The microwave scatterometer is one of the main instruments for providing global ocean wind fields with …
WebSpace-based scatterometers are active instruments designed to measure ocean surface vector winds. Observations from several spaceborne scatterometer missions have been collected over the past 25 years, including the C-band European Space Agency (ESA) ERS-1/2 and ASCAT sensors beginning in 1991 to current, the Ku-band NASA‘s NSCAT … WebJun 1, 2024 · In practice, the scatterometer winds are retrieved from a set of backscatter measurements at multiple azimuths, incidences, and polarizations ... As expected, both bias and SD values increase with rain rate. For sea surface winds below 10 m/s, the retrieved CSCAT wind speed is significantly overestimated ...
WebOct 10, 1978 · Unlike a scatterometer, SAR has high (sub-kilometre) resolution and at the same time provides a panoramic survey of the ocean surface. Yet, SAR probes the surface at the single and a priori indeterminate angle to wind speed; hence the wind vector retrieval is only by the NRCS value, even with the help of well-calibrated SAR, is generally unfeasible. WebJul 29, 2010 · In this letter, we generate a temporal/spatial matchup data set between QuikSCAT scatterometer and RADARSAT-1 synthetic aperture radar (SAR) wind products in offshore waters along the U.S. West Coast. Analysis of the resulting three-year database shows that, in general, the wind products from both sensors have characteristics similar …
WebSep 6, 2003 · In a nutshell, scatterometers transmit pulses of microwaves with relatively short wavelengths (relatively high frequencies) and measure the backscatter from the wind-roughened ocean. The faster the winds are, the rougher the ocean surface, and the more radiation that backscatters to the scatterometer.
WebSurface wind speed is the dominant variable over most of the ocean for the magnitude of air sea exchange of trace gases, as well as wind stress, heat and water vapor. Satellite data of surface winds are now produced routinely by scatterometers on several satellites. The scatterometer produces wind vectors by taking advantage of the backscatter being a … can i take a bike on the metro in dcWebSea Surface Winds also known as Ocean Surface Vector Winds (OSVW) for some techniques Winds, ...
