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.

System and method for detecting chemical species from a remote sensing platform

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.

Gas flux determination using airborne DIAL LIDAR and airborne wind measurement

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.

Determination of gas flux using airborne dial lidar

A process for characterizing the phase of an organic material in a thin film comprises employing a reference spectrum library for potential phases, subjecting the film to a vibrational spectroscopy measurement to obtain a resulting spectrum; and comparing the resulting spectrum to those in the reference library to characterize the phase of the organic material.

Methods and systems for obtaining a target fluid map of a survey area using a differential absorption LIDAR (DIAL) system are provided. Pulse bursts are transmitted toward the survey area, where each pulse burst includes an off-line pulse and at least one on-line pulse. Pulse bursts, each being associated with a measurement point, are received from the survey area. A concentration path length (CPL) corresponding to a respective on-line pulse, a spatial location associated with the CPL, and an error associated with the CPL are determined for each measurement point. The CPL for each measurement point is arranged within the survey area to form the target fluid map.

System and method for multi-target fluid concentration detection and mapping

A method of finding a temporal location of a reflected pulse in a system for remotely measuring characteristics of a target scene. The method includes steps of: (a) transmitting a pulse burst of two or more pulses toward the target scene; (b) capturing a copy of the pulse burst transmitted in step (a); (c) measuring an inter-pulse separation between at least two pulses in the pulse burst captured in step (b); (d) receiving a signal reflected from the target scene; (e) determining a temporal location of a first pulse in the signal received in step (d); and (f) determining a temporal location of a second pulse in the signal received in step (d) based on the inter-pulse separation measured in step (c). Step (a) may include transmitting an OFF-line pulse and at least one ON-line pulse in the pulse burst toward the target scene from a differential absorption LIDAR (DIAL) system, where the OFF-line pulse and the ON-line pulse are combined pulses, each individually generated from a separate pulsed laser transmitter and each having a different wavelength.
