성층권 내에 존재하는 에어로졸의 생성 원인은 무엇인가? | 성층권 내에 존재하는 에어로졸은 화산 폭발로 인해 생성된 많은 양의 에어로졸과 이산화황(SO2)와 같은 가스상 물질들이 성층권으로 한꺼번에 유입됨으로 인해 생성된다. 지난 1991년 6월 15일에 분화한 필리핀의 피나튜보 화산(Mt. | |
성층권 에어로졸은 어떤 영향을 미치는가? | , 2002). 성층권 에어로졸은 10 km 이상의 고도에 비균질적으로 분포하여 대륙범위 또는 그이상의 전 지구적 범위의 대기질과 지구 복사강제력에 영향을 미쳐 기후변화에 높은 영향을 미친다(Chin and Jacob, 1996; Grafet al., 1997; Haywood and Boucher, 2000; Longhurst et al. | |
본 연구에서 개발한 성층권 에어로졸 라이다의 경우, 관측의 정확성을 어떻게 높였는가? | 성층권 에어로졸 라이다는 성층권 영역까지의 원거리 관측을 위해 ND: YAG 레이저 파장의 1064 nm 와 532 nm 탄성산란채널을 중심으로 입자의 비구형성 관측을 위해 532 nm에 편광 채널을 확장하였다. 또한 효율적인 원거리 신호 처리를 위해 아날로그 디지털 변환(analog-to-digital)과 광자계수방식 (Photon counting)의 검출기를 동시 적용하여 관측의 정확성을 높였다. |
