Characterizing diurnal variability in power plant carbon emissions in Asia: A top-down estimation approach constrained by geostationary NO2 and OCO-3 CO2 observations

Key Points

• Diurnal variability in carbon emissions was observed across multiple power plants in Asia, showing significant fluctuations.
• Emissions were estimated using a top-down approach that incorporates geostationary observations of NO2 and CO2.
• Data from satellite measurements provided insights into the timing and scale of emissions during different times of the day.
• This analysis highlights the importance of continuous monitoring for improved environmental regulation and climate strategies.
