AI Technical Summary
Existing greenhouse gas monitoring instruments exhibit nonlinear responses. Directly using linear response methods to correct observation data can lead to measurement deviations exceeding the quality targets of the World Meteorological Organization/Atmospheric Observation Program. There is a lack of targeted and effective error correction methods.
A scientific calibration and verification process is constructed, integrating multiple correction methods and establishing an effectiveness judgment and selection mechanism. Through multi-point calibration sequences, single-point calculation, error correction factor acquisition, verification analysis, and weighted distance calculation, the optimal correction method is selected to achieve accurate correction of greenhouse gas nonlinear response errors.
It ensures that greenhouse gas measurement deviations meet quality standards, improves the accuracy and reliability of analytical data, is applicable to a variety of detection instruments and gases, and has good versatility and scenario adaptability.
