A technique for removing the effect of migrating birds in 915-MHz wind profiler data

A method is described and evaluated for decreasing artifacts in radar wind profiler data resulting from overflying, migrating birds. The method proces ses the prerecorded, averaged spectral data of a wind profiler to derive ho urly wind profiles during conditions of frequent backscattering from birds. Comparison with in situ measurements revealed a significant improvement ov er the "traditional," online processing routine. When both the traditional method and the proposed new method are applied to an extended dataset, a pr actical procedure can be implemented to detect periods with significant bir d-caused artifacts.
