The Meteorological Office processes ERS-1 fast-delivery products from the scatterometer, the altimeter, and the Along-Track Scanning Radiometer. Wind vectors, wind speed, wave height, and sea-surface temperature data are all validated against the operational atmospheric, wave, and sea-surface temperature analyses. Summary statistics from these validations are presented. The ERS-1 data appear to have smaller errors than the ship data currently used.
Surface winds from the scatterometer should both improve the atmospheric analyses and forecasts, and improve the fluxes from the atmospheric analyses used to drive wave and ocean models. The wave data have made it worthwhile for the first time to develop a wave assimilation, rather than deducing the wave field solely from the history of atmospheric forcing. Results from preliminary parallel tests measuring the impact of these data sources are presented. Further work developing the model assimilation schemes is needed, before they give the full improvement hoped for.
