摘要： A system and method for estimating an amount of substance released into an ambient thereby creating a plume includes at one sensor adapted to be positioned at the plume and making multiple concentration measurements of the released substance at multiple times. A computer-based analyzer system is programmed with an algorithm. The analyzer receives concentration measurements from the at least one sensor and the algorithm generates an estimate of amount of substance released as a function of the multiple concentration measurements and the time of the measurements.

摘要： 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.
摘要翻译：使用路径平均浓度测量来估计从特定位置释放的物质的量的系统和方法。在可能的物质释放位置周围的适当位置设置一个或多个开放路径感测系统，并且被调谐以检测感兴趣的特定物质。随着时间的推移收集特定物质的路径平均浓度测量值，并传达给开放路径返回计算算法。该算法计算多个时间段的时间平均测量。然后用时间平均测量进行反向计算，以估计物质的释放速率和总释放量。

摘要： A system for predicting a source location and release rate of a hazardous substance uses the basic knowledge of meteorological information (wind speed, direction, and stability) and two or more concentration measurements of the chemical released. Horizontal dispersion information obtained from surface meteorological data at sensor locations are used to narrow the search domain for the release location, reducing the computational cost. Each of the possible release locations in the search domain and possible release rates are evaluated in a process that predicts a concentration measurement at a sensor, based on a predicted location and release rate. The location and release rate that results in a least error when compared to an actual concentration measurement at the sensor are chosen as the source of the chemical and the release rate from the source.
