Dropsonde observations were made by the U.S. Air Force along
the "Ptarmigan" track of its reconnaissance program. This track
was mainly over the Beaufort Sea and the western Arctic Ocean.
Vertical profiles of geopotential height, temperature, and
dew point temperature at various pressure levels are available
for eleven years between 1950 and 1961 (excluding 1953) for the
lower troposphere mainly below 500mb.
In comparing the locations on the dropsondes to the locations
on the aircraft reconnaissance reports in ds360.0, DSS found
that the dropsonde longitudes are off by 10 degrees. For
dropsondes over the Western Hemisphere, the positions are 10
degrees east of the aircraft positions, and for the Eastern
Hemisphere, they are 10 degrees west of the aircraft
1950 to 1961

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.
