A Tropical Wind Climatology Derived from Aircraft Data, 1960-1973

| DOI: 10.5065/XDWN-H202

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 It has likely been superseded by a newer, improved dataset.


Long term monthly mean winds were derived from a collection of aircraft data, which were obtained from two sources: 1) operational Global Telecommunication System (GTS) reports collected by the Honolulu National Weather Service and the U.S. Navy, and 2) aircraft logs from many routes which often were not reported over the GTS. Aircraft winds were summarized for each month in 5-degree latitude-longitude squares. Monthly-averaged rawinsonde data were then combined with these summarized aircraft winds in manual analyses of streamlines and isotachs. This dataset's 2.5-degree grids of wind speed and direction were digitized from the manual analyses.

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.
