This data set contains radiosonde data. High resolution 6-second data has been received at NCDC since April 1995 and archived as digital data set DSI-9948, Six-second Upper Air Data. The requirement to include the U and V components of wind has initiated this data set, DSI-6211. The software to convert DSI-9948 to DSI-6211 was provided by the Joint Office of Science Support (JOSS) of the Office of Programs of the University Corporation for Atmospheric Research (UCAR). The software did a format conversion as well as made some improvements to data calculations. DSI-6211 has data from 1998 to the present. Geographic coverage is the United States of America including Alaska and Hawaii, Puerto Rico, the US Virgin Islands, US territories in the Pacific, and nations in the Pacific hosting offices of the US National Weather Service (NWS). Major parameters deal with a typical radiosonde release and are time, pressure, dry bulb temperature, dew point temperature, relative humidity, U component of wind, V component of wind, wind speed, wind direction, ascension rate, longitude, latitude, elevation and azimuth, altitude and various quality codes for each parameter. To make a wide range of climatic data available to researchers and the public. Micro ART Observation and Rework Programs Technical Document 19910301 Washington, D.C.
