ERA-40 Global Upper Air Satellite Wind Observation Feedback Record Reports ECMWF > European Centre for Medium-Range Weather Forecasts NSF National Center for Atmospheric Research Published: 2005-11-09 Valid: 1978-12-01 to 2002-08-31 climatologyMeteorologyAtmosphere ERA-40 Global Upper Air Satellite Wind Observation Feedback Record Reports include upper air satellite wind observation (SATWND) feedback record reports from SATWNDs used in the ECMWF 45-year reanalysis (ERA-40) covering the period from September 1957 to August 2002. SATWNDs, from multiple data sources, were assimilated into an ECMWF model and produced ERA-40. Select variables include zonal and meridional wind speed components at the observed pressure level. The metadata generated during the ERA-40 quality control data assimilation process were appended to the input observations. The final combination of input observations and feedback metadata are called feedback record reports.
