Pilot Chart Summary Data
These one-degree and five-degree quadrangle summaries give the observation count for an eight-point "wind rose", and means and standard deviations for: wind speed, pressure, air temperature, wet-bulb temperature, sea surface temperature, air-sea temperature difference, and wave height. Also included are light and heavy superstructure icing potential and frequency of gales. The general period summarized is 1850 to 1970, but the actual period summarized varies by ocean basin. These long-term monthly averages were used to produce the U.S. Navy Marine Climatic Atlas.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ 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.
