The computational complexity of the SeaWinds spatial response function requires that a method of tabularization and interpolation be used. Here the pre-computed tables and the interpolation code are available.

Inputs to the interpolation routines are the antenna azimuth angle, the satellite orbit time and the desired polarization.

This code and tables are made available as a public service. While the code has been tested on HP linux platforms, no claim is made for the correctness or suitability of the code or tables for any purpose. Any use of this code is made at the user's own risk. Source code may be freely copied and modified as long as (1) original authorship is acknowledged, (2) code is not distributed for profit without prior authorization from David G. Long at Brigham Young University, and (3) the paper I.S. Ashcraft and D.G. Long, "The spatial response function of SeaWinds backscatter measurements", in "Earth Observations Systems VIII", W.L. Barnes, ed., Proceedings of SPIE Vol. 5151, pp. 609-619, 3-6 Aug 2003 is ited.
