Localization analytics algorithms and methods

A system comprising:

• a vehicle configured to move through a plurality of spatial positions and generate spatial position data corresponding to the plurality of spatial positions;
• one or more in situ trace-gas concentration sensors disposed on the vehicle and configured to generate a plurality of in situ point source trace-gas concentration measurements at the plurality of spatial positions, the one or more in situ trace-gas concentration sensors measuring trace-gas in situ;
• a weather station generating a meteorological data containing wind vector;
• a ground control station (GCS) having a processor with addressable memory, the processor configured to:
• receive the plurality of in situ point source trace-gas concentration measurements;
• receive the spatial position data of any one of the vehicle or the one or more in situ trace-gas concentration sensors and corresponding to the received in situ point source trace-gas concentration measurements;
• receive the meteorological data corresponding to each in situ point source concentration trace-gas measurement;
• determine if each in situ point source trace-gas concentration measurement is an elevated ambient trace-gas concentration;
• generate a back trajectory for each elevated ambient trace-gas concentration based on the spatial position where the elevated ambient trace-gas concentration occurs and the meteorological data corresponding to the spatial position where the elevated ambient trace-gas concentration measurement occurs;
• store the position of each generated back trajectory in a grid;
• sum the stored positions of the generated back trajectories within each cell of the grid;
• and
• determine a probability of a trace-gas source location corresponding to the summed stored positions in the grid;
• a display configured to communicate with the GCS and generate an overlay showing the probability of the trace-gas source location.
