Substance Release Estimation Using Path-Averaged Concentration Measurements
First Claim
1. A computer-implemented substance release estimation method for a substance released into a surrounding medium thereby creating a plume, the method comprising:
- calculating a plurality of path-averaged concentration measurements of the substance for a plurality of time instants;
averaging the plurality of path-averaged concentration measurements over the plurality of time instants to obtain a time-averaged measurement of the plurality of path-averaged concentration measurements; and
estimating a release rate of the substance as a function of the time-averaged measurement of the plurality of path-averaged concentration measurements.

Abstract
A system and method for using path-averaged concentration measurements for estimating the amount of substance being released from a particular location. One or more open-path sensing systems are set up in appropriate locations around possible substance release sites and tuned to detect a particular substance of interest. Path-averaged concentration measurements of the particular substance are collected over time and communicated to an open-path back calculation algorithm. The algorithm calculates time-averaged measurements for a plurality of time periods. Back calculation is then performed with the time-averaged measurements to estimate the release rate and the total release of the substance.
