S. Department of Defense author NSF National Center for Atmospheric Research publisher 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. completed datahelp@ucar.edu pointOfContact notPlanned dataset ASCII dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral AIRCRAFT U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Platforms DROPSONDES U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Instruments EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > DEW POINT TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > ATMOSPHERIC PRESSURE MEASUREMENTS EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 1950 1961 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 2.986 https://gdex.ucar.edu/datasets/d358000/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d358000/dataaccess/ https Data Access Related Link download none asNeeded
