ECMWF WMO Global Tropospheric Analysis


Twice daily, 00Z and 12Z, analyses from the ECMWF global operational model from 1980 to 1989 are archived in this dataset. The data are on global 2.5 degree grids including 5 variables on 7 pressure levels. Derived monthly mean grids are added to the archive.

Temporal Range:
1980-01 to 1989-12

Data License:
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.
