Data sets

Airborne Data from the Fertilizer Emissions Airborne Study (FEAST). Nitrous Oxide, Carbon Dioxide, Carbon Monoxide, Methane, Ozone, Water Vapor, and meteorological variables over the Mississippi River Valley E. A. Kort, A. Gvakharia, M. L. Smith, and S. Conley https://doi.org/10.7302/Z2XK8CRG

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.
