[DOI: 10.21982/M8DK9D ] Tabularized SeaWinds Spatial Response Function
Precise computing the SeaWinds spatial response function (SRF) is complicated and requires significant computation detailed knowledge of the orbit geometry and instrument processing. This code computes an approximate SRF for SeaWinds based on precomputed tables. The SRF is computed as a function orbit position, antenna rotation angle, and polarization. The full footprint "egg" SRF is approximated by a 2d polynomial while the "slice" SRF is approximated by a shaped boxcar. Details are given in the referenced paper.
