Embodiment Construction

[0017] Such as figure 2 As shown, an airborne near-infrared CO 2 The vertical column concentration telemetry device is based on the airborne platform. The system uses a two-dimensional motor-driven attitude adjustment platform to adjust the infrared telescope system to measure ground reflected light and solar scattered light. The reflective optical introduction system composed of reflection by the mirror 5 and focus by the focusing lens 6 directly converges on the incident slit of the spectrometer 7 in the thermostat 8, and is imaged on the InGaAs detector after being dispersed by the spectrometer. The near-infrared spectrum signal obtained by digital conversion is sent to the computer; the near-infrared spectrum signal is processed by the radiative transfer model to calculate the CO 2 The weight function curve of the weight function, the application of the least squares method to analyze the CO 2 The vertical column concentration information, combined with geographical loc...

Abstract

The invention discloses onboard near-infrared CO2 vertical pillar concentration telemetering equipment. The onboard near-infrared CO2 vertical pillar concentration telemetering equipment comprises an infrared telescope system, a posture adjustment platform driven by a two-dimension motor, an optic guiding system, a spectrograph detector system positioned in a constant temperature box, a GPS (global position system) and a data processing system, wherein the posture adjustment platform is adopted to adjust the infrared telescope system to measure the ground reflected light and the sun scattered light, the obtained light signal is directly converged on a spectrograph positioned in the constant temperature box through the optic guiding system and is imaged on a detector through the dispersion of the spectrograph to obtain signal data; the data processing system is utilized to process signal data to resolve the CO2 vertical pillar concentration information, meanwhile, the device is internally provided with the GPS, the GPS is communicated with a computer through a USB (Universal Serial Bus) data line, and the GPS and the geographical location information are combined to obtain the region distribution of the CO2 vertical pillar concentration. The onboard near-infrared CO2 vertical pillar concentration telemetering equipment provided by the invention is capable of realizing the rapid monitoring of the region distribution of the CO2 vertical pillar concentration, and solves the problem that atmosphere CO2 gas telemetering measure is lacked at present.

Description

technical field [0001] The invention belongs to the technical field of optical measurement, in particular to a 2 Near Infrared Spectroscopy Airborne Measurement Device for Vertical Column Concentration Telemetry. Background technique [0002] CO 2 It is an important greenhouse gas and plays an important role in the greenhouse effect of global warming. In order to be able to effectively control CO 2 emissions, we need to understand the causes of CO in our country's atmosphere 2 source and distribution of emissions, which requires monitoring of emissions from various sources. In addition, timely and accurate emission data are used as input parameters in the air pollution forecasting model, which plays an important role in improving the accuracy of forecasting and forecasting. my country currently measures CO 2 The methods are mainly chemical methods and gas chromatography, which are mainly ground point measurements, and cannot obtain the CO in the whole layer of the atmo...
