Short summary
MAX-DOAS is a technique that can be used to measure pollutant concentrations and vertical profiles in the atmosphere via remote sensing of sky-scattered light with a telescope. Measuring SO2 is particularly challenging because of low light intensities in regions where SO2 absorbs solar radiation. Here, we performed experiments that document inaccuracies in these measurements as a function of spectral fitting windows. We provide recommendations for measuring SO2 with greater accuracy.
