Short summary

We present a new flight system to measure the atmospheric trace gases N₂O, CO₂, CO, and H₂O. We use a novel calibration technique to correct altitude-dependent artifacts that have hindered similar instruments. In-flight null-tests and comparison with other flight-proven instruments provide validation. This high-precision, high-accuracy system provides opportunities for airborne studies to improve our understanding of N₂O emission processes.
