Abstract
Spatiotemporal distributions of CO2 obtained from the greenhouse gases observing satellite (GOSAT) over China from 2010 to 2017 and influence factors are presented in this study. It shows an annual increase and a seasonal cycle. The CO2 annual growth rate was about 2.34 ppm year(-1), with the highest value being in spring and the lowest in autumn. Yearly variations in the CO2 over eight economic regions are prominent, the regions with higher CO2 concentration also have higher increase rate. Some factors affecting variations in CO2 are analysed in this study. There is a stronger negative relationship between CO2 and MODIS vegetation products. Population density and energy consumption are anthropogenic factors in increasing CO2 concentration, and CO2 variation shows a high correlation with population density in eight economic regions [coefficient of determination (R-2) = 0.76]. CO2 and energy consumption also have a better correlation (R-2 > 0.66) in the most regions.
