新一代的紫外/维斯/近红外卫星仪器，如GOME（自1995年起），SCIAMACHY（自2002年起），OMI（自2004年起）和GOME-2（自2006年起），使人们能够在大波长范围（240-790 nm）内以中等光谱分辨率测量来自地球的后向散射太阳辐射。SCIAMACHY仪器还包括近红外光谱通道，从测量的光谱中可以确定平流层和对流层的几种重要痕量气体（如O_3、NO_2、OClO、HCHO、SO_2、BrO、H_2O）以及云、气溶胶和地面特性。SCIAMACHY仪器由于其扩展的光谱范围，还可以在近红外波段反演温室气体（CO_2，CH_4）和CO，几乎所有的对流层痕量气体都是首次被这些仪器观测到的。从卫星数据可以调查其时间和空间变化。此外，不同的来源可以被定性和量化。所得出的全球分布可以作为输入和验证大气模型。在这里，我们给出了这些新的仪器和数据产品的现状，以及它们最近在各种大气和海洋现象的调查中的应用的概述。
A new generation of UV/vis/near-IR satellite instruments like GOME (since 1995), SCIAMACHY (since 2002), OMI (since 2004), and GOME-2 (since 2006) have allowed one to measure backscattered solar radiance from the Earth with moderate spectral resolution over a large wavelength range (240–790 nm). The SCIAMACHY instrument also includes additional spectral channels in the near-IR. From the measured spectra several important stratospheric and tropospheric trace gases (e.g. O_3, NO_2, OClO, HCHO, SO_2, BrO, H_2O) as well as clouds, aerosols and surface properties can be determined from space. Because of its extended spectral range, the SCIAMACHY instrument also allows the retrieval of greenhouse gases (CO_2, CH_4) and CO in the near-IR. Almost all of the tropospheric trace gases have been observed by these instruments for the first time. From satellite data it is possible to investigate their temporal and spatial variation. Also, different sources can be characterized and quantified. The derived global distributions can serve as input and for the validation of atmospheric models. Here we give an overview of the current status of these new instruments and data products and their recent applications in the investigation of various atmospheric and oceanic phenomena.
