Abstract

Claims (29)

1 . A method for automated record quality determination for pollutant emissions, comprising:

collecting atmospheric data for an area via an anemometer of a sensor assembly placed at a location downwind from an emissions site;

collecting concentration data for pollutant emissions via an airborne pollutant sensor of the sensor assembly at the location;

processing the atmospheric data to determine a quality of the atmospheric data based on a wind direction detected by the anemometer at the location;

processing the concentration data for pollutant emissions to determine a quality of the concentration data;

producing a combined quality metric from the quality of the atmospheric data and the quality of the concentration data;

determining if the combined quality metric is of a high level or a low level;

determining the combined quality metric changes from the high level to the low level based on the wind direction, wherein an end of a stable period is defined by the change in the combined quality metric; and

reducing a power consumption and increasing a bandwidth of the method by transmitting, after the end of the stable period, a statistical average of the concentration data for pollutant emissions during the stable period.

2 . The method for automated record quality determination for pollutant emissions according to claim 1 , wherein the processing of the atmospheric data to determine the quality of the atmospheric data determines a low atmospheric quality.

3 . The method for automated record quality determination for pollutant emissions according to claim 1 , wherein the processing of the atmospheric data to determine the quality of the atmospheric data determines a medium atmospheric quality.

4 . The method for automated record quality determination for pollutant emissions, according to claim 1 , wherein the processing of the atmospheric data to determine the quality of the atmospheric data determines a high atmospheric quality.

5 . The method for automated record quality determination for pollutant emissions according to claim 1 , wherein the quality of the concentration data comprises a low quality.

6 . The method for automated record quality determination for pollutant emissions according to claim 1 , wherein the quality of the concentration data comprises a high quality.

7 . The method for automated record quality determination for pollutant emissions according to claim 1 , further comprising performing further processing of the combined quality metric based on the combined quality metric being of a high level.

8 . The method for automated record quality determination for pollutant emissions according to claim 7 , further comprising performing an inversion of the concentration data for pollutant emissions.

9 . The method for automated record quality determination for pollutant emissions according to claim 8 , further comprising producing a notification that a reliable source term estimation has occurred.

10 . The method for automated record quality determination for pollutant emissions according to claim 8 , further comprising:

based on the combined quality metric being of a low level, producing a notification that a low confidence measurement has been made.

11 . The method for automated record quality determination for pollutant emissions according to claim 10 , wherein:

the atmospheric data is a first set of atmospheric data;

the concentration data is a first set of concentration data; and

the method further comprises:

collecting a second set of atmospheric data;

collecting a second set of concentration data; and

performing the method again using the second set of atmospheric data and the second set of concentration data.

12 . The method for automated record quality determination for pollutant emissions according to claim 11 , wherein transmitting the statistical average of the concentration data for pollutant emissions comprises:

transmitting the statistical average of the concentration data for pollutant emissions to a wireless system.

13 . The method for automated record quality determination for pollutant emissions according to claim 12 , wherein the wireless system comprises at least one of a cellular network or a satellite link.
