Abstract In this study, spatial and temporal variations of radiative forcing(RF) and mean temperature changes due to green-house gases(CO 2 , CH 4 , and N 2 O) emitted from commercial aircraft were examined based on the simplified expres-sion at the airports in Korea during 2009~2010. The radiative transfer model (SBDART) was used to comparewith the RF and mean temperature changes calculated from the simplified expressions for greenhouse gas CO 2 . TheRF simulated by the SBDART was about 67% higher than that of the simplified expression, on average. Thehighest mean RF(up to 9.0 mW/m 2 for CO 2 ) and mean temperature changes(up to 9.7×10 -5 �K/day for CO 2 ) for allGHGs occurred at Ulsan airport during the study period, whereas the lowest RF and temperature changes atYangyang (for CO 2 ) and Sacheon airports (for CH 4 and N 2 O). In the case of CH 4 and N 2 O, their effects to the RFand mean temperature change were negligible compared to CO 2 .
