Abstract:
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.

Metadata Record:
Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
