Short summary
To mitigate N2O emissions, the processes behind the emissions need to be well understood. Because of this, we developed a new measurement setup for precise and simultaneously fast airborne in-situ N2O measurements. We developed an empirical water vapor correction enabling measurements in regions with high humidity and found no significant influence of different flight parameters on the measurements during two campaigns. This setup can help to measure N2O in humid and undersampled regions.
