NCEP Daily Northern Hemisphere Tropospheric Analyses for 1973 January to 1997 March

| DOI: 10.5065/6KFW-3Z50

This dataset contains twice daily gridded Northern Hemisphere analyses from NCEP's operational model on 47-by-51 and 65-by-65 polar-stereographic grids centered on the North Pole. Available parameters include geopotential height, temperature, stream functions, thickness, and vertical velocity for various levels and layers through the troposphere.

NCEP prepared the 65-by-65 analyses, and were an advancement over the 47-by-51 "B3" analyses. Later NCEP made global analyses, from which the 65-by-65 analyses were interpolated. To continue the 47-by-51 analyses, NCAR/CISL/DSS extracted them from the 65-by-65 grid.

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.
