Short summary
The performance of the MARGA (Monitor of AeRosols and GAses in ambient air) instrument in measuring speciated nitrogen and sulfur fluxes is evaluated for the first time. The results demonstrate that the MARGA instrument can be used to make accurate measurements of speciated nitrogen and sulfur deposition. These measurements are urgently needed to evaluate chemical transport models and develop risk assessments and mitigation strategies to protect ecosystems from nutrient and acidic deposition.
