gov.noaa.ncdc:C00183 National Climatic Data Center, NESDIS, NOAA, U.S. Department of Commerce Unknown tabular digital data http://www.ncdc.noaa.gov U.S. Upper Air Rawinsonde is historical digital data set DSI-5810, archived at the National Climatic Data Center (NCDC). Data are of two types: thermodynamic data (TDAT) and minute wind direction and speed (WDAT). Major parameters in 'TDAT' are station id, observation id, elapsed time of data levels, pressure height, temperature, moisture, equipment performance and ship position (if applicable). Major parameters in 'WDAT' are station id, observation id, wind direction and speeds for each available minute of winds aloft data. Unique ship numbers which were established by NCDC are included in these data. To make a wide range of climatic data available to researchers and the public.

'TDAT' has a few instances where the height data may be incorrect. Corrections may be computed from the pressure, temperature, and moisture using the hydrostatic equation. 'WDAT' total times may occasionally be incorrect. Unknown Completeness information not available. Not derived from another data set. Unknown Low level stations (RAOB reports) are identified by the letter 'l' in column 1 (TDAT record only). Moisture may be reported in relative humidity, dew point temperature, or dew point depression. RECORD DESCRIPTION - THERMODYNAMIC DATA "TDAT" ELEMENT: WBAN Station Number POSITION: 1-5 ELEMENT: Year POSITION: 6-7 ELEMENT: Month POSITION: 8-9 ELEMENT: Day POSITION: 10-11 ELEMENT: Nearest hour of release POSITION: 12-13 Note: If a ship releases a balloon within +/- 1.5 hours of 00GMT or 12 GMT, the hour of release is recorded as 00 or 12 GMT. (Ships only) ELEMENT: Elapsed time since release (1/10 of a minute) POSITION: 14-17 Note: If this field contains a "-" the record is only a filler ID for a missing observation. ELEMENT: Pressure (millibars to 1/10) POSITION: 18-22 ELEMENT: Height (nearest geopotential meter) POSITION: 23-27 ELEMENT: Temperature (nearest 1/10 degrees Celsius) POSITION: 28-31 ELEMENT: Relative Humidity (nearest whole percent or dew point temp. or depression to 1/10 degree Celsius) POSITION: 32-34 ELEMENT: Flight Equipment Performance Code (See addendum "C" NWS of FMH-3) POSITION: 35-38 ELEMENT: 1 = Begin doubtful temp. 2 = Begin doubtful temp. and altitude 3 = Begin doubtful altitude and end doubtful temp. 4 = Begin doubtful altitude 5 = End doubtful temp. POSITION: 39 ELEMENT: Blank POSITION: 40-73 ELEMENT: May be blank or contain a "1". Useful for NCDC purposes only POSITION: 74 ELEMENT: Blank POSITION: 75 ELEMENT: Ship position POSITION: 76-80 Note: First digit is octant of globe Second two digits are nearest whole degree of latitude Fourth and Fifth digits are nearest whole degree of longitude - units and tens digits only. RECORD DESCRIPTION - WINDS ALOFT DATA "WDAT" ELEMENT: WBAN or ship number POSITION: 1-5 ELEMENT: Year POSITION: 6-7 ELEMENT: Month POSITION: 8-9 ELEMENT: Day POSITION: 10-11 ELEMENT: Nearest hour of release POSITION: 12-13 Note: If a ship releases a balloon within +/- 1.5 hours of 00GMT or 12 GMT, the hour of release is recorded as 00 or 12 GMT. ELEMENT: Beginning minute of elapsed time for a record. Each record contains up to nine consecutive minutes of wind direction and speed. Records continue to be written with each beginning minute a multiple of 9 for the entire flight. POSITION: 14-16 ELEMENT: Wind direction in whole degrees and wind speed in whole knots for each minute of available data. POSITION: 17-70 ELEMENT: The total elapsed time of the winds aloft observation. This element is blank on all except the last record. POSITION: 71-73 ELEMENT: This element may contain a blank or a "2". Useful for NCDC purposes only. POSITION: 74 ELEMENT: Ship's Position POSITION: 75-80 Note: First digit is octant of globe Second two digits are nearest whole degree of latitude Fourth and Fifth digits are nearest whole degree of longitude - units and tens digits only.
