Passive microwave imager on WSF-M1 for ocean surface winds, tropical cyclone intensity and additional environmental data.
WSF-M Microwave Imager is a conically scanning passive microwave imager on WSF-M1 for ocean-surface vector winds, tropical-cyclone intensity, and additional environmental data products. The WSF-M1 spacecraft launched on 2024-04-11, and the imager became active in August 2024 [1]. Its channel set spans 10.85, 18.85, 23.8, 36.75, 37.3, and 89 GHz [1]. The 10.85, 18.85, and 36.75 GHz channels provide full Stokes outputs [1]. The fully polarimetric channels support ocean wind-vector observations by digitally correlating V-pol and H-pol inputs to compute third and fourth Stokes states [2]. Passive microwave radiometry is demonstrated on WSF-M1 [1].
