Active/Passive Ocean Wind Vector Measurements from GPM Core Observatory

In this paper, we demonstrate the feasibility of remote sensing of ocean vector wind (OVW) from the Global Precipitation Measurement (GPM) satellite. By combining its active normalized radar cross section (σ
⁰
), and passive microwave brightness temperature (Tbs) measurements, ocean surface wind vectors were retrieved and validated by comparison with collocated ASCAT wind products. The algorithm is described, and the results are presented.
