HALOE 자료를 이용한 중위도 지역의 오존농도 추이분석

Abstract

The ozone concentration measured by HALOE(Ver. 19) from Oct. 1991 to Dec. 2003 is used for analyzing thevariation of ozone concentration. The HALOE loaded in UARS is observing several gases in the atmosphere, from10 km to 80 km. Fourier analysis of these data in the middle latitude northern hemisphere is reported in this paper.To detect any possible long term trends, the fourier transformed time series was back transformed after removingsignals with time periods of less than 6 months. Although the results clearly show the strong annual cycle, it isdifcult to show any long term trends from the fourier series.We also compared the ozone volume mixing ratio’s from HALOE with that from the ground-based radiometryto evaluate the accuracy of microwave observation at Sookmyung Women’s University.
