The data have been derived from radiosondes, pilot balloons, registering balloons and kites and has been subjected to a systematic quality assessment. CHUAN has focused on collecting data for pre-1957 . This product is the "V1.7" corrected (quality controlled) data with no bias or radiation correction applied ("CDC" in CHUAN documentation). There are other products available in "V1.7", like corrected data with bias and radiation corrections and the raw (non quality controlled) soundings, along with others, that are not available at this time. A new version is expected to be available in mid 2014. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png ASCII dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral BALLOONS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 1904-01-01 2007-03-27 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 17745.701 https://gdex.ucar.edu/datasets/d352000/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d352000/dataaccess/ https Data Access Related Link download none asNeeded
