FASTEX Commercial Aircraft Dataset
AIREP - Data from AIREP flight weather report (Commercial Aircraft AIREP Data) AMDAR - Data from AMDAR flight weather report (Commercial Aircraft AMDAR Data) ACAR - Data from ACAR flight weather report (Commercial Aircraft ACAR Data) Organization of the file : ------------------------ Each data line contains 24 fields, separated by spaces. The contents and sizes of the 24 fields that appear in each data record are as follows (Unit for Unit or Code table (from the Manual oncodes (WMO-No. 306), International codes volume I.2, part B), Form for FORTRAN Format, Miss for Missing value) : No Parameter Unit Form. Miss -- --------- ---- ----- ---- 1 Timestamp for the creation of the row YYYYMMDDHHMISS a14 2 Aircraft flight number a14 3 Collecting date/time (UTC) YYYYMMDDHHMISS a14 4 Latitude dec.degr f8.3 5 Longitude dec.degr f8.3 6 Quality control flag (0=good, 1=bad) a4 7 Wind direction degr f6.1 -999 8 Wind speed m/s f6.1 -999 9 Air temperature deg.
