Abstract

The invention discloses a real-time telemetry system and a real-time telemetry method of greenhouse gas column concentration. The real-time telemetry system comprises a fixed station building and a sun follower, wherein the station building is provided with an automatic sunroof; the sun follower is installed on a fixed platform in the station building and used for receiving sunlight from the sunroof, thereby automatically following the sun; emergent light of the sun follower passes through a sample tank to enter an infrared spectrometer, and an output end of the infrared spectrometer is connected with a computer; a micro weather station and a wireless data transmission antenna are installed outside the station building and connected to the corresponding input end of the computer; measured spectra and numerical simulation calculated spectra based on an atmospheric radiation transmission model are obtained simultaneously; and the greenhouse gas column concentration of various kinds is obtained in real time by using a nonlinear least-squares iteration method. According to the real-time telemetry system and the real-time telemetry method, the defects of the greenhouse gas three-dimensional high space-time resolution measurement technology are overcome, calibration data can be provided for airborne and satellite telemetry, and local long-term greenhouse gas observation results can be provided.

technical field [0001] The invention relates to the fields of environmental monitoring and protection, and optical remote sensing, and specifically refers to a real-time remote measurement system and method for greenhouse gas column concentration. Background technique [0002] Accurate measurement of greenhouse gas concentration is of great significance in the fields of energy conservation, emission reduction, environmental safety, and climate change. At present, for the concentration of greenhouse gases in the atmosphere at a specific location, gas chromatography and mass spectrometry analysis methods of sampling surface air and in-situ measurement monitoring methods are mainly used; for specific areas, airborne active and passive telemetry are used; for global-scale greenhouse effects, satellite Load passive telemetry and model simulation studies. In addition, a small number of tall tower measurements have also been reported. Among these measurement methods and s...

Problems solved by technology

Among these measurement methods and systems, the measurement equipment of gas chromatography and mass spectrometry is cumbersome and expensive, and the sampling and measurement period is long; the results of airborne greenhouse gas measurement are limited, and the change of greenhouse gas concentration on a continuous time scale cannot be obtained; satellite greenhouse gas telemetry and Model simulation results need to be calibrated with foundation column concentration measurements

None of these technical means can obtain the concentration of greenhouse gas column from the surface to the top of the atmosphere at a specific location with high time resolution.
