ERA-40 Monthly Means of Upper Air Potential Vorticity Surface Data

| DOI: 10.5065/WG28-FV82

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 It has likely been superseded by a newer, improved dataset.


Monthly means of upper air potential vorticity level data from ECMWF ERA-40 reanalysis project are in this dataset.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the 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.
