    SCATTEROMETER High Resolution Ocean Wind field and Sea Ice probability
    (1831) recent views
    Last update: 25 September 2017

    The ASPS Level 2 High Resolution products contain, for each node: the radar backscattering sigma nought for the three beams of the instrument, the four aliased wind solutions (Rank 1-4 wind vector) and the de-aliased wind vector flag, the sea-ice probability and sea-ice flag, the YAW quality flag.

    The wind retrieval is performed with the CMOD5N geophysical model function derived by ECMWF to compute the neutral winds rather than 10m winds.

    ASPS L2.0 High resolution products are provided with a spatial resolution of 25x25 km and a grid spacing of 12.5 km. One product covers one orbit from ascending node crossing.
