Abstract
Mixing ratio of carbon dioxide (CO2) for 2018 from CAMS database was compared with those from in situ and remote measurements carried out in Petergof (St. Petersburg, Russia). The analysis shows that the differences in surface CO2 concentration from CAMS and measurements and the correlation coefficients significantly varied depending on months. Ground-based and satellite spectroscopic measurements of column averaged CO2 mixing ratio are in a good agreement with CAMS. Even though the CAMS data which was analyzed in current research requires further development, our results have shown that the CAMS data can be used in resolving an inverse problem to derive anthropogenic emissions for the territory of Saint-Petersburg and its suburbs.
