Preliminary Validation of FENGYUN-3E GNOS-II GNSS-R Wind Prodcut

China’s FengYun-3E meteorological satellite was launched on July 5, 2021. The GNOS-II onboard the satellite is a payload that can combine GNSS reflectometry (GNSS-R) and GNSS radio occultation (GNSS RO). It can also receive signals from GPS and BeiDou (BDS) satellites. This paper introduces the GNSO-II payload and its early on-orbit GNSS-R wind product. The characteristics of reflectometry using BDS signals was discussed. The early on-orbit wind product was validated by the comparison with ECMWF reanalysis wind data. The GNSS-R winds retrieved by GPS and BDS signals were compared.
