Atmospheric carbon dioxide (CO2)
Cavity ring-down spectroscopy system
1 Scope
This standard specifies the installation environment based on the optical cavity ring down spectroscopy observation system to observe the background of the atmosphere of carbon dioxide (CO2) concentration, the principle
And the system composition, performance requirements.
This standard applies to optical cavity ring down spectroscopy atmospheric background concentration of atmospheric CO2.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Cavity ring-down spectroscopy cavityring-downspectroscopy
Based on the single-wavelength laser beam entering the optical cavity back and forth between the mirror reflection oscillation, the energy cut off after the light source decay over time, decay
The principle that the speed is related to the loss of the optical cavity (including transmission and scattering) and the absorption of the measured component (medium) in the cavity, the loss of the specific optical cavity itself
For the constant, the attenuation of light energy is proportional to the content of the measured components, in order to quantify the content of the measured components.
2.2
Online observation in-situmeasurement
Situ observation of the site, direct measurement of the components under test at the target site.
2.3
Working standard gas standardgas
To clean the air as the stamina, the concentration of components to be tested known mixture.
2.4
Target gas targetgas
The concentration (close to the concentration of the components to be measured) is known as the working gas as the test gas, repeated measurements at regular intervals for monitoring
Measure the stability of the system.
2.5
Nominal assignedvalue
The standard concentration (molar ratio, mol/mol) given after calibration of the standard gas at the upper level.
2.6
Sample gas samplinggas
Contains the components to be tested, their concentration is known or unknown gas samples.
3 installation environment
3.1 site requirements. Atmospheric CO2 concentration can basically represent the characteristics of regional atmospheric background site; should be located in the main source of pollution or residential Sheng
Windward windward or crosswind, and avoid easily lead to adverse weather phenomena (such as static wind, affixed to the temperature inversion) of the terrain (such as depression) and the nearby iron
Roads, highways, mining, chimneys, tall buildings.
3.2 Inlet requirements. Should be located above the ground vegetation canopy 15m.
