The two data sets in this product are the Earth-located radar backscatter
(sigma-0), and vector wind measurements, collocated in 25 km x 25 km wind
vector cells. The selected wind vector is flagged. Backscatter
measurements are provided globally over land, ice and oceans. The derived
wind vector solutions (all ambiguities) and the selected wind vector are
only available over oceans. The data are organized in a swath-based
format, with each record consisting of a cross-track row of 48 wind vector
cells (24 on each side of the satellite subtrack). Each record contain a
number of variables, sigma-0's and related information, such that
investigators can re-retrieve the winds using their own model function
should they wish. Each file covers one NSCAT revolution and typically
consists of 1624 data records.  S2 to S43 are batch directories.
