ERA-40 Global Upper Air Radiosonde Observation Feedback Record Reports

ERA-40 Global Upper Air Radiosonde Observation Feedback Record Reports include 6 hourly upper air radiosonde observation (RAOB) feedback record reports from RAOBs used in the ECMWF 45-year reanalysis (ERA-40) covering the period from September 1957 to August 2002. RAOBs, from multiple data sources, were assimilated into an ECMWF model and produced ERA-40. Select variables found in the reports include temperature, pressure, height, relative humidity, specific humidity, zonal wind, and meridional wind speed components. Data may be available at mandatory or significant levels from 1000 millibars to 1 millibars. 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.
