Monthly Climatological Grid Data for Levels Aloft

| DOI: 10.5065/Z4EA-B620

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 It has likely been superseded by a newer, improved dataset.


The USAF Environmental Technical Applications Center (ETAC) created these monthly climatologies of temperature and winds for the Northern and Southern Hemispheres, and geopotential height for the Northern Hemisphere. Generally, the data input period from approximately 150 stations was the 5-year period from January 1956 through December 1960, but some data into 1962 were also used. The climatologies are available on 5-degree latitude/longitude grids separately for eight vertical pressure levels between 850 and 50 millibars, inclusive.

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.
