DOAS
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. Additional information available at "http://snake.irf.se/optlab/hut2/index.html" [Summary provided by the Swedish Institute of Space Physics] (en)
