The altitudinal potential source contribution function (PSCFa) method was developed by considering topography and height of back trajectories. The PSCFa calculated on the contributions of trans-boundary transport to the hourly mean concentrations of aerosol optical depth (AOD) of the Aerosol Robotic...

PSCF 모델의 기능은 무엇인가? | 이후 장거리 이동 오염원에 대한 통계적 유의성을 높이기 위해, Potential Source Contribution Function(PSCF) 모델이 사용되었다(Zeng and Hopke, 1989). PSCF 모델은 역궤적 모델 결과와 대기 중 오염물질의 측정값 중 고농도 측정값을 이용하여 오염물질의 발생지역 확률을 모사한다. 이와 유사한, 측정 농도에 로그를 적용한 Concentration Field Analysis (CPA) 모델(Weiss-Penzias et al. | |
대기 중 에어로졸의 발생원인은 어떻게 구분되는가? | 대기 중 에어로졸은 산업 활동에 의한 인위적 원인과 자연적 원인으로 나뉘며, 대류권 내 연직 및 수평으로 분포되어 있다(Ramachandran and Kedia, 2013). 해염입자, 황산염이온, 그리고 미량 원소 등의 자연발생 주성분과 함께, 인위적 원인에 의해 발생된 에어로졸의 적지 않은 양이 이와 혼재되어 있다(Habib et al. | |
인위적 발생에 의해 증대된 복사 강제력의 정량적 산출 문제를 보완하기 위한 방법은 무엇인가? | , 2013). 이를 극복하기 위해, 오래전부터 Moderate Resolution Imaging Spectroradiometer(MODIS), Multiangle Imaging Spectroradiometer(MISR), Ozone Monitoring Instrument(OMI), Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) 등의 인공위성 원격탐사로부터 광범위한 범위의 에어로졸 광학 두께(Aerosol Optical Depth, AOD) 및 물리화학적 특성을 관측하였다(Kahn et al., 2010). 또한, 지상 AOD 연직분포(More et al., 2013) 관측으로부터 에어로졸의 광학 특성 및 복사 강제력과, 인공위성 관측 결과와 연계하여 대기 중 에어로졸의 종합적인 분포 특성을 분석하였다 (Kim et al., 2016a; Bibi et al. |
