To accurately understand anthropogenic influences in the atmosphere as well as the regional carbon cycle, detailed and precise measurements and monitoring of greenhouse gas concentrations in urban areas are needed. Seoul is a megacity that is also a major source of anthropogenic emissions of CO2 as well as other greenhouse gases and pollutants. In this study, we analyze a combination of ground, aircraft, and satellite measurements of CO2, CO, and CH4 made during a campaign from 19-22 February 2021 in the Seoul metropolitan area. We use ground-based CO2 concentration and air pollutant data from the Seoul National University CO2 Measurement (SNUCO2M) and AirKorea monitoring stations, respectively. In addition, we use column-averaged abundances of CO2, CO and CH4 measured from the ground using two portable Fourier transform infrared (FTIR) spectrometer EM27/SUNs and measured from space using the Orbiting Carbon Observatory-2 (OCO-2) and Sentinel-5 Precursor TROPOspheric Monitoring Instrument (TROPOMI). Lastly, we quantify greenhouse gas concentrations in the atmosphere across Seoul with the aircraft measurements made during the campaign period. Through this unique opportunity, we analyze the atmospheric concentrations utilizing various measurements from ground to space as well as the combustion efficiency across the Seoul metropolitan area using ratios of CO/CO2 and CH4/CO2.
