AUTOMATED DETECTION AND QUANTIFICATION OF GAS EMISSIONS
A method for detecting and quantifying gas emissions from a satellite image comprises obtaining an image of an area of interest, determining an amount of variation in light intensity within the image, and correlating the amount of variation in light intensity within the image to a gas concentration of a gas emission located in the area of interest.
DRONE FOR MEASURING DATA REPRESENTATIVE OF AMOUNTS OF AT LEAST TWO GASES PRESENT IN THE ATMOSPHERE AWAY FROM THE GROUND AND ASSOCIATED METHOD
This drone comprises a sensor for measuring representative data, comprising at least one measurement cell that is open to the atmosphere, at least a first laser source configured to inject, into the measurement cell, a first laser beam at a first wavelength characteristic of a first gas to be detected and a second laser source configured to inject, into the measurement cell, a second laser beam at a second wavelength characteristic of a second gas to be detected. The measuring sensor comprises a detector common to the two laser sources, said detector being configured to detect a first measurement signal originating from the measurement cell and resulting from injection of the first laser beam into the measurement cell and a second measurement signal originating from the measurement cell and resulting from injection of the second laser beam into the measurement cell.
REMOTE SENSING OF NATURAL GAS LEAKS
A method of detecting natural gas releases that includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of methane in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.
Systems and methods for modeling water quality
A system, method, device and computer-readable medium for creating an ensemble model of water quality. The ensemble model is generated by determining a set of optimal component models for spectral regions of a body of water, and combining the optimal models. The optimal models can be based on remote sensing data, including satellite imagery. A K-fold partition approach or a global approach can be used to determine the optimal component models, and the optimal component models can be combined through spectral space partition rules to generate an ensemble model of water quality. The ensemble model not only has improved water quality prediction ability, but also has strong spatial and temporal extensibility. The spatial and temporal extensibility of the ensemble model is fundamentally important and desirable for long-term and large-scale remote sensing monitoring and assessment of water quality.
SHORT-WAVE INFRARED SENSOR FOR IDENTIFYING BASED ON WATER CONTENT
An optical system operating in the near or short-wave infrared wavelength range identifies an object based on water absorption. The system comprises a light source with modulated light emitting diodes operating at wavelengths near 1090 and 1440 nanometers, corresponding to lower and higher water absorption. The system further comprises one or more wavelength selective filters and a housing that is further coupled to an electrical circuit and a processor. The detection system comprises photodetectors that are synchronized to the light source, and the detection system receives at least a portion of light reflected from the object. The system is configured to identify the object by comparing the reflected light at the first and second wavelength to generate an output value, and then comparing the output value to a threshold. The optical system may be further coupled to a wearable device or a remote sensing system with a time-of-flight sensor.
GROWTH INFORMATION MANAGEMENT APPARATUS, GROWTH INFORMATION MANAGEMENT SYSTEM, METHOD FOR CONTROLLING GROWTH INFORMATION MANAGEMENT APPARATUS, AND GROWTH INFORMATION MANAGEMENT PROGRAM
A growth information management apparatus is provided, which can accurately ascertain a growth situation of plants or the like regardless of a positional change of an equipment where the apparatus is mounted. A growth information management apparatus 100 emits a measuring beam to a plant P and acquires growth information on the plant, based on received reflected light, with the growth information management apparatus being mounted on another equipment 1. The growth information is corrected based on change information on the irradiation direction of the measuring beam according to a positional change of the other equipment.

An active remote sensing system is provided with an array of laser diodes that generate light directed to an object having one or more optical wavelengths that include at least one near-infrared wavelength between 600 nanometers and 1000 nanometers. One of the laser diodes pulses at a modulation frequency between 10 Megahertz and 1 Gigahertz and has a phase associated with the modulation frequency.

The detection system uses a lock-in technique that synchronizes pulsing the one laser diode. The active remote sensing system is configured to be mounted on a vehicle or an airborne platform to provide distance information based on a time-of-flight measurement.
