Zusammenfassung:The XCO 2 concentration across climate type remains largely unexplored. This paper examined carbon concentration across climate types in India using Level 2 data (378,050 sample points) of column-averaged CO 2 concentrations (XCO 2 ) that were collected from the orbiting carbon observatory (OCO-2) in September 2014 to August 2015. Temperate climate ranks first among climate types in terms of energy demand and carbon dioxide (CO 2 ) emissions due to continued intensive urbanization. However, urbanization in temperate climate was not the most important predictor of higher XCO 2 concentration in India. On the contrary, the annual XCO 2 mean concentration in tropical climate was higher than annual XCO 2 mean concentration in temperate climate. In contrast to the typical theory, temperate climate were not a dominant determining factor upon dense XCO 2 concentration. A clear verification has been made for the typical theory for CO 2 concentration increased across global urbanization. The individual climate types are found to be more appropriate in explaining global CO 2 concentration, rather than urban location. It was demonstrated that the climate types could be used effectively as an indicator to global CO 2 concentrations since the OCO-2 signature of 378,050 sample points can present objective area-wide evidences as a basis for regional climate comparisons. It is anticipated that this research output could be used as a valuable reference to a strong theoretical basis to compare carbon concentrations across climate types.
