Short summary
- A new algorithm to retrieve nitrogen dioxide by Brewer spectrophotometers was developed. - Direct sun and zenith sky data recorded at the Izaña observatory were processed with the new algorithm and compared to co-located reference instruments. - The measurement uncertainty was thoroughly determined by using a Monte Carlo technique. - The new algorithm can be applied to more than 60 Brewers around the world.
