Short summary
Sulfur dioxide (SO2) is a key precursor to aerosol formation, particularly in remote marine environments, ultimately affecting cloud properties and climate. Accurate quantification of atmospheric SO2 is therefore crucial. This work compares a custom-built laser-based instrument to two commercial SO2 analysers during measurements from a large research aircraft. Our results show that this custom-built system offers greater sensitivity at time resolutions required for aircraft measurements.
