SeaWinds Wind Retrieval Quality Assessment
The SeaWinds on QuikScat scatterometer is the first in a series of new scanning pencil-beam Ku-band scatterometers. The viewing geometry is significantly different than previous fan beam instruments, resulting in different characteristics in the retrieved winds. In this paper we provide an assessment of the reliability of the SeaWinds ambiguity selection using a SeaWinds data-only algorithm. An...
متن کاملHigh resolution wind retrieval for SeaWinds
The SeaWinds instrument on the QuikSCAT satellite was designed to measure near surface winds over the ocean at a nominal resolution of 25 km with daily global coverage. Recently, reconstruction and resolution enhancement algorithms have been applied to the QuikSCAT measurements to generate high resolution backscatter fields. These high resolution fields make it possible to retrieve the wind at ...
متن کاملHigh Resolution Wind Retrieval from SeaWinds
SeaWinds is a Ku-band pencil-beam scatterometer launched in 1999 on the QuikSCAT mission. It is designed to make nominally 25 km resolution observations of vector winds over the ocean. However, by taking advantage of resolution enhancement and its dense sampling characteristics, the wind can be retrieved at much higher resolution, albeit with greater noise. Winds with resolutions as fine as 2.5...
متن کاملUltra High Resolution Wind Retrieval for SeaWinds
The SeaWinds series of scatterometer instruments were designed to measure vector winds over the ocean at a nominal resolution of 25 km. However, the radar backscatter measurements from which the wind is inferred are made at finer resolution than this. Further, the spatial sampling of the backscatter measurements can support reconstruction of finer scale backscatter values which can then be used...
متن کاملAn assessment of SeaWinds on QuikSCAT wind retrieval
[1] The scatterometer ocean wind retrieval process produces several possible solutions or ambiguities at each point, requiring a separate ambiguity selection step to infer a unique wind vector field. An ambiguity selection error occurs when the selected wind vector is not the closest ambiguity to the true wind. The current ambiguity selection routine for SeaWinds is ad hoc, but performs well un...
