SCIAMACHY limb spectra

The space-borne spectrometer SCIAMACHY aboard ESA’s Envisat satellite has been observing the Earth’s atmospheric radiance since April 2002. The instrument is recording spectra which cover the ultra-violet, visible, and near infra-red spectral regions almost continuously. The measurements are performed in three different geometries. In this article, we show for the first time limb scattering spectra which cover SCIAMACHY’s entire spectral range. The atmospheric features are separated from the solar and instrumental features by a normalization procedure. Prominent features of all three types are discussed. 2004 COSPAR.
