Atmospheric CO2 Inversion Error Analysis and Accuracy Verification
In this study, the atmosphere major greenhouse-gases monitor instrument (GMI) loaded on the GF-5 satellite platform is used to measure the column concentration of atmospheric greenhouse gases CO2 and CH4. To ensure the accuracy of the greenhouse gas inversion in GMI remote sensing data, the influence of aerosol and other factors in greenhouse gas inversion on inversion results is analyzed and used as the correction factor of the inversion algorithm. Given this, the GMI inversion results are verified using the total carbon column observing network (TCCON) site. Furthermore, results show that the GMI near-infrared inversion results exhibit a low bias with -1.06±2.93×10 -6(-0.26±0.72%), and the inversion accuracy is within 1%.
