This study aims to quantify commercial aircraft emissions, CO, NOx and HC, with 1 km × 1 km resolution at Suvarnabhumi airport based on 2015 data. The number of actual departure flights and aircraft engines were acquired and the emission factors were applied to calculate the emissions of overall flying cycle, namely aircraft taxi, take-off, initial-climb and climb-out. In addition, the route map and each flying cycle were created from XY coordinates with a Geographic Information System. The emissions at each coordinate within 1 km × 1 km grid along with route map were interpolated to provide the spatial emissions for each spatial layer of the flying cycle. The overall results showed that annual emissions were about 598 ktons for CO, 4220 ktons for NOx, and 112 ktons for HC. The aircraft taxi mode accounted about 545 ktons of CO emission, 104 ktons of NOx, and 100 ktons of HC annually, while the emission during take-off mode of CO was 24 ktons, 2200 ktons for NOx, and 6 ktons for HC. The annual emission during the initial-climb mode accounted about 12, 990 and 3 ktons of CO, NOx and HC, respectively. In climb-out mode, the annual emissions of CO, NOx and HC were 17, 926 and 3 ktons, respectively. The highest emissions of CO, NOx and HC from spatial analysis occurred during taxi mode for CO and HC at the end of the runway, northward of the airport. The highest NOx found during the take-off mode, at the center of the runway.
