gov.noaa.ncdc:C00056 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov U.S. Upper Air Standard Levels is historical digital data set DSI-9735, archived at the National Climatic Data Center (NCDC). Major parameters which make up this file include station id and position, for all standard levels, height of standard pressure levels, temperature, relative humidity, wind direction and speed, number of levels in observation. The observational data included in this file constitutes a coverage of Air Force, Navy land and sea ships, National Weather Service, Canadian, foreign cooperative and signal corps stations, U.S. controlled ocean weather stations, military sea transport ships that take radiosonde observations. This data set is produced from radiosonde observations recorded in the data blocks on forms WBAN 31 A, B and D (adiabatic charts) and from digital computer output for automatic RAOB stations by various sources. Related files include upper air (rawinsonde) observations, upper air (rawinsonde) global coverage. To make a wide range of climatic data available to researchers and the public.
