Remote sensing methods have emerged as powerful tools in the efforts to understand the carbon and water cycles, as well as the distributions and concentrations of both abundant and trace gas species in the atmosphere. Among these techniques is multi-axis differential optical absorption spectroscopy, or MAX-DOAS. MAX-DOAS entails the collection of solar radiation spectra using a telescope coupled to an ultraviolet-visible spectrometer. By changing the angle of the telescope line of sight relative to the horizon, different regions of the atmosphere can be probed. As the majority of scattering events occur within the lowest 5 to 10 km of the atmosphere, the technique is sensitive to tropospheric constituents.
