최근 동북아 지역의 대기오염물질 농도는 감소하는 추세이다. 이러한 농도 감소에는 배출량 변화뿐만 아니라 기상 요인의 변화가 함께 작용한 것으로 보고된다. 따라서, 농도 변화로부터 배출량 변화 정도를 정량화하기는 어렵다. 한편, 배출량 변화를 분석하기 위해 국가 배출량 목록을 이용할 수 있으나, 상향식으로 작성되는 방법론적 특성상 누락 배출원이 존재할 수 있으며, 작성연도와 배포연도가 달라 배출량의 변화를 빠르게 파악하기 어렵다. 이러한 배출량 목록의 불확도를 고려하여 많은 연구에서 위성 관측자료 기반의 배출량 역모델링 방법을 제안하였다. 단, 위성 관측자료의 경우 시/공간 해상도가 낮으며, 배출 고도를 추정하기 어려운 한계를 가진다. 이에 본 연구에서는 국가 배출량 목록 기반의 대기질 모사 ...
