Abstract:

Global Aircraft Reports is historical digital data set DSI-6380, archived at the National Climatic Data Center (NCDC). DSI-6380 is a historical collection of many types of meteorological upper air reports that NCDC has received from the National Centers for Environmental Prediction (NCEP). Data are global. The different types of reports are: A. PIREPS (pilot reports) were produced from a pilot talking to a ground observer. There were no latitude and longitude for location. Instead, there were a radial direction and distance from an observing site. NCEP decoders (computer and human) translated the location to latitude and longitude. B. AIREPS (air reports) had multiple sources, but were primarily from Air Traffic Control (ATC). These were semi-automatic reports from aircraft to ground and were encoded by ATC personnel. These reports were a free code and were primarily for over ocean reporting. Aircraft using this reporting procedure had Inertial Navigation System (INS) equipment, so the winds were usually of high quality. Instead of latitude/longitude, location was provided by a three or four letter identifier. NCEP decoders translated the letter identifiers to lat/long. NCEP received AIREPS from different countries over the World Meteorological Organization (WMO) sponsored Global Telecommunications System (GTS). C. Aircraft to Satellite Data Relay (ASDAR) was used on a few widebody aircraft of British, Continental, and Quantas Airlines flying predominately between Europe and North America or within these regions. However, others flew to destinations in Asia, Africa, Australia, and South America. Reports were communicated from the aircraft via geostationary meteorological satellites. Because of the automation characteristics, data was usually of high quality. D. Australian Reports were restricted to line of sight transmission. Since almost every commercial aircraft in Australia had reporting equipment, there were a tremendous number of Australian reports. Frequency of reports was one every 7 minutes during level flight, and one every 10hPa or 50hPa during ascent and descent (with the higher frequency applying to the lower part of the atmosphere). Because of the automation characteristics, data was usually of high quality. Reports were received by NCEP over the GTS. E. Global Weather Intercept (GWIP) network was PIREPS and AIREPS received by the Air Force Weather Agency (AFWA) at Offutt AFB, NE and sent to NCEP. These reports were from the Southern Hemisphere, South America, and the Western Pacific. F. ARINC Communications Addressing Reporting System (ACARS) provided reports over the continental United States and Alaska. Frequency of reports was every 5 to 10 minutes at flight level and during ascents and descents around major airports. Because of the automation characteristics, data was usually of high quality. NCEP collected these reports from ARINC (Aeronautical Radio Incorporated). Aircraft reports are sorted by marsden square and date: 10 degree marsden square, 1 degree Marsden box, tenth of degree Marsden subbox, year, month, day, hour, minute, receipt hour, and receipt minute. Possible major parameters include: barometric height, temperature, relative humidity, dew point depression, wind direction and speed, aircraft in clouds code, and turbulence code. To make a wide range of climatic data available to researchers and the public. SUPPLEMENTAL INFORMATION: data set CURRENTNESS REFERENCE: Ground Condition
