AbstractThe National Aeronautics and Space Administration (NASA) RapidScat scatterometer on board the International Space Station (ISS) provides observations of surface winds which can be assimilated into numerical weather prediction (NWP) forecast models. In this study, we assess the data quality of the RapidScat Level 2B surface wind vector retrievals, and the impact of those observations on the National Oceanic and Atmospheric Administration (NOAA) Global Forecast System (GFS). The RapidScat is found to provide quality measurements of surface wind speed and direction in non-precipitating conditions, and provide observations that add both information and robustness to the global satellite observing system used in NWP models. We find that with an assumed uncertainty in wind speed of around 2 m/s, the RapidScat has neutral impact on the short-range forecast of surface wind vectors in the Tropics, but improves both the analysis and background field of surface wind vectors. However, the deployment of RapidScat on the ISS presents some challenges for use of these wind vector observations in operational NWP, including frequent maneuvers of the spacecraft which could alter instrument performance.
