Water Vapor Winds in the Arctic Region Retrieved from FY-3D MWHS-II 183.31-GHZ Brightness Temperature

In this study, an Atmospheric Motion Vector (AMV)-based method for retrieving wind vectors using 183.31-GHz water vapor absorption channels is introduced. The effectiveness of this approach is validated through a comparative analysis with the ERA5 reanalysis data and the wind product derived from the Visible Infrared Imaging Radiometer Suite (VIIRS). Furthermore, this methodology demonstrates a complementary performance with the VIIRS wind product, suggesting its potential for enhancing the diversity of wind field data.
