Source Geolocation using Backward Trajectories
from Measurement Locations


  • Run backward trajectories from various locations corresponding with high measured values
  • By superimposing these trajectories it may be possible to determine the source location
  • For a more accurate geo-location, it is necessary to sample a variety of different flow orientations
