Validation of SeaWinds on QuikSCAT Cell Location
Increased interest in high resolution ocean wind measurements, as well as excellent past performance, has led to the development of enhanced resolution applications of SeaWinds on QuikSCAT scatterometer data. An essential requirement of this development is the validation of the cell location accuracy the latitude and longitude of each measurement. This paper discusses two methods of validating ...
متن کاملTen Years of SeaWinds on QuikSCAT for Snow Applications
The scatterometer SeaWinds on QuikSCAT provided regular measurements at Ku-band from 1999 to 2009. Although it was designed for ocean applications, it has been frequently used for the assessment of seasonal snowmelt patterns aside from other terrestrial applications such as ice cap monitoring, phenology and urban mapping. This paper discusses general data characteristics of SeaWinds and reviews...
متن کاملValidation of QuikSCAT Radiometer Rain Rates using the TRMM Microwave Radiometer
The primary mission of the SeaWinds scatterometer on the QuikSCAT satellite is to infer surface wind vector from ocean backscatter measurements. Occasionally the backscatter measurements are contaminated by the presence of rain; therefore a reliable method of identifying rain is needed. Fortunately, the SeaWinds scatterometer simultaneously obtains active (scattering) and passive (emission) mea...
متن کاملA QuikScat/SeaWinds Sigma-0 Browse Product
Following up on the successful NSCAT mission, the QuikScat/SeaWinds scatterometer (Qscat) provides normalized radar cross section ( o) measurements of the Earth's surface at unprecedented coverage and resolution. While originally designed for wind observation, scatterometers have proven useful in a variety of land and ice studies. To aid in the selection of regions and time periods for study, a...
متن کاملPrecipitation Measurements using the QuikSCAT Radiometer - Geoscience and Remote Sensing Symposium, 2003. IGARSS '03. Proceedings. 2003 IEEE International
Microwave brightness temperatures are obtained from the SeaWinds scatterometer on the QuikSCAT satellite. These QuikSCAT Radiometer (QRad) measurements are used to infer instantaneous oceanic rain rates using a statistical retrieval algorithm that is based upon collocated TMI measurements. QRad instantaneous rain rate measurements have been binned in 0.5 hour local time windows onto a 0.5° x 0....
