For Twin Otter: Horizontal distance (km) of coincident point For Twin Otter: Latitude of coincident point For Twin Otter: Longitude of coincident point For Twin Otter: Altitude (km) at coincident point 0 7 This file provides the closest coincidences of each aircraft to the NPOL ground site at a given time. For a coincidence, an aircraft must pass within 25 km horizontally of the ground site location. The information in this file is all based on the navigational recorder or Meteorological Measurement System data of each aircraft, available in their respective archive files. Please see those files for details. 47226 24.535 25.708 -81.465 0.172 47236 23.976 25.714 -81.465 0.129 47246 23.423 25.720 -81.464 0.093 47256 22.884 25.725 -81.463 0.052 47266 22.340 25.731 -81.462
