SeaWinds on QuikSCAT L2B Ocean Wind Vectors in 12.5km Slice Composites

This dataset has been superseded by Version 3: http://podaac.jpl.nasa.gov/dataset/QSCAT_LEVEL_2B_OWV_COMP_12 . This QuikSCAT Level 2B dataset contains science-quality ocean surface wind vector retrievals from the NASA SeaWinds scatterometer. The Version 2 L2B data continues to be openly distributed to allow sufficient time for community acceptance of the Version 3 dataset. The retrievals are provided on a non-uniform grid within the swath at 12.5 km pixel resolution. Higher resolution is achieved through a slice composite technique in which high resolution slice measurements from L1B data are composited into a 12.5 km wind vector cell. The increased sampling resolution enables users to obtain wind vectors 10 km closer to shore when compared to the 25 km L2B dataset. Each L2B file corresponds to a specific orbital revolution (rev) number, which begins at the southernmost point of the ascending orbit. An ASCII inline quality report (Q2B) has been generated for each L2B file; each Q2B file provides statistics of various quality elements pertaining to the processing of a specific L2B file. These wind vector retrievals have been processed using the QSCAT-1 geophysical model function. This is the official dataset produced by the QuikSCAT Project through the SeaWinds Processing and Analysis Center (SeaPAC). The SeaWinds instrument is a conical scanning pencil-beam radar, with dual-beam and dual-polarization capability, operating at Ku-band to provide all-weather ocean surface wind vector retrievals.
