Аннотация
The results of studying spatial–temporal CO2 variations near St. Petersburg in 2014–2017 based on satellite measurements (OCO-2 satellite) and ground-based spectroscopic and local measurements are presented. According to satellite data, the full amplitude of the spatial–temporal variations for the average CO2 mixing ratio (XCO2) amount to 57.7 ppm (over 14%). The maximal XCO2 spatial variations during 1 day of observations (March 17, 2015) were 46.8 ppm (more than 10%).
A comparison of CO2 satellite and ground-based spectroscopic measurements has shown that ground-based measurements in the NDACC observation system after the correction of systematic differences from the TCCON system can be used to validate satellite measurements. Ground-based local measurements of the near-surface CO2 mixing ratio at Peterhof do not correlate either with spectroscopic ground-based or satellite measurements due to both mesoscale CO2 variations and significantly different spatial averaging kernels of direct and remote measurements.
