摘要

SCIAMACHY是一种先进的光谱仪，覆盖宽光谱范围(240 nm至2400 nm)，中等分辨率(0.2至1.4 nm)，可测量与臭氧化学和温室辐射研究相关的大量大气微量气体。SCIAMACHY将是定于2000年底发射的ESA ENVISAT大气化学模块的一部分。SCIAMACHY将以边缘/最低点交替视角观测地球大气，以大约3公里的垂直分辨率和30/spl倍/60公里/sup / 2/水平分辨率采样相同的空气体积。本文简要介绍了该仪器的概念、工作方式和检索数据产品。给出了最近的一些仪器测试结果和检索数据精度模拟。

SCIAMACHY: an atmospheric chemistry instrument on ENVISAT

SCIAMACHY is an advanced spectrometer covering a wide spectral range (240 nm to 2400 nm) at medium resolution (0.2 to 1.4 nm) that measures a large number of atmospheric trace gases relevant for ozone chemistry and greenhouse radiation studies. SCIAMACHY will be part of the ESA ENVISAT atmospheric chemistry module scheduled for launch at the end of the year 2000. SCIAMACHY will observe the Earth atmosphere in alternate limb/nadir view, sampling the same air volume with approx 3 km vertical and 30/spl times/60 km/sup 2/ horizontal resolution. This paper presents a brief account of the instrument concept, its operation modes and its retrieved data products. Some recent instrument test results and retrieved data accuracy simulations are presented.
