| hasSummary |
-
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 position.
