  skos:definition """The Differential Optical Absorption Spectrometer (DOAS)
instrument consists of grating spectrometers covering the
visible and near ultraviolet spectral region. Zenith-scattered
sunlight is collected by simple one-lens telescopes and fed via
optical fiber bundles into the spectrometers, where atmospheric
absorption spectra are obtained. The instrument runs
automatically.
