Greenhouse gas satellites can provide consistently global CO2 data which are important inputs for the top-down inverse estimation of emissions and their dynamic changes. By tracking greenhouse emissions, policymakers businesses identify areas where reductions needed most implement effective strategies to reduce impact on environment. Monitoring gases provides valuable scientists studying climate change. The requirements monitoring verification support capacity drive payload design future satellites. In this study, we quantitatively evaluate performance satellite in detecting plumes from power plants based an improved Gaussian plume model, with focus impacts spatial resolution satellite-derived XCO2 precision under different meteorological conditions. simulations indicate that enhanced significantly improve detection capability satellite, especially small-sized below 6 Mt CO2/yr. satellite-detected maximum enhancement strongly varies wind condition. For a 0.7 ppm 2 km, it recognize plant 2.69 CO2/yr at speed m/s, while its emission needs be larger than 5.1 if is expected detected 4 m/s.
