Abstract
|
|
|
Emissions of air pollutants and greenhouse gases (GHGs) from aircraft activities at 11 small-scale airports were
investigated using the emissions and dispersion modeling system (EDMS) version 5.1.3 during the two year period of
2009~2010. The number of landing and take-off (LTO) at these airports was dominant for the aircraft type B737, accounting
for more than 60% of the total LTOs. Out of the 11 small-scale airports, Gwangju (GJ, RKJJ) airport was the largest emitter
of air pollutants and GHGs, whereas Yangyang (YY, RKNY) airport was the smallest emitter. The emissions of NOx and
VOCs in 2010 at the 11 airports ranged from 1.9 to 83 ton/y and 0.1 to 17 ton/y, respectively. In 2010, the emissions of CO2
ranged from 394 to 21,217 ton/y. The emissions of most air pollutants (except for NOx and PM10) and GHGs were estimated to be the highest in taxi-out mode. The highest emissions of NOx and PM10 were emitted from climb-out and approach modes, respectively. In addition, the total LTOs at the 11 small-scale airports accounted for the range of 9.3~9.9% of those at four major international airports in Korea. The total emissions of air pollutants and GHGs at the 11 airports ranged from 4.8 to 12% of those at the four major airports.
