Starting August 27, 2025, NCAR’s Climate Data Gateway (CDG) and Geoscience Data Exchange (GDEX) will be retired. The Research Data Archive (RDA) is now the central home for these datasets.
RDA Web UI and API services, including search and subset request applications, are currently unstable due to systems issues. We are working to resolve these issues by early next week. We apologize for the inconvenience.
This historical dataset is recommended for ancillary use only and not as a primary research dataset. It has likely been superseded by a newer, improved dataset.
Abstract:
The ERA-40 model level variances and covariances with respect to the monthly means are in this dataset.

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.
