Short summary
We evaluated spectra from a scanning spectrometer network for the monitoring of volcanic gas emissions using a modelled background spectrum. Statistical methods were applied in order to improve the quality of the spectroscopic evaluation. We used this technique to assess the robustness of standard retrievals at two volcanos: Nevado del Ruiz (Colombia) and Tungurahua (Ecuador).
