Abstract:
1. A method for estimating a maximum concentration of one or more target species along a line of measurement, the method comprising: (a) providing a first monitor capable of producing a signal indicative of one of a path-integrated concentration and a path-averaged concentration of the one or more target species along a line of measurement; (b) selecting a line of measurement comprising a first end point and a second end point; (c) positioning the first monitor along the line of measurement at a monitoring path defined by the first end point and the second end point of the line of measurement; (d) positioning at least one point monitor at one or more predetermined locations between the first end point and the second end point of the line of measurement, wherein the at least one point monitor is capable of producing a signal indicative of one or more concentrations of the one or more target species at the one or more predetermined locations; (e) simultaneously measuring one of the path-integrated concentration and path-averaged concentration and the one or more concentrations of the one or more target species at the one or more predetermined locations; and (f) correlating a temporal variation between one of the path-integrated concentration and path-averaged concentration and the one or more concentrations of the one or more target species at the one or more predetermined locations to estimate a maximum concentration of the one or more target species along the line of measurement.
