摘要： A system for obtaining emission flux of a gas plume, emanating from a source, includes an airborne differential absorption lidar (DIAL) system for determining multiple concentration path length (CPL) values along a flight path; and an airborne wind measuring system (WMS) for determining a wind vector at the aircraft altitude. Also included is a processor for receiving the multiple CPL values determined by the DIAL system and the wind vector determined by the WMS. The processor uses the CPL values to compute either (a) an area-integrated concentration (AIC) value or (b) an average concentration value over a cross-plume extent, defined along the length dimension of the flight path. The processor also scales the wind vector to the near ground altitude level of the gas plume to obtain a scaled wind vector. The emission flux is obtained by multiplying either the AIC value or the average concentration value with a component of the scaled wind vector. The component of the scaled wind vector is defined by a vector perpendicular to the length dimension of the flight path.

摘要： A system is provided for determining emission rate of a gas from a source. The system includes a selector for designating an in-plume area extending across a plume of gas. The in-plume area includes a length dimension greater than a width dimension. The system also includes a processor for determining an area-integrated concentration value for the in-plume area. The system further includes a wind vector received by the processor. The processor determines the emission rate of the gas based on the area-integrated concentration value and a vector component of the wind vector.

摘要： A remote sensing system includes a transmitter for transmitting an online signal and first and second offline signals toward a target. A receiver receives a returned online signal and first and second returned offline signals from the target. A processor is provided for determining (a) a first ratio based on the returned online signal and first offline signal, and (b) a second ratio based on the returned online signal and second offline signal. A filter is also provided for correlating the first ratio with the second ratio for determining whether the returned online, first offline and/or second offline signals are useable. The returned online, first offline and second offline signals are used to compute first and second concentration path lengths (CPLs) of a column of air between a target and the remote sensing platform.
