ARISTO-2015 Airborne Oxygen Instrument (AO2)

The Airborne Oxygen Instrument (AO2) data for the ARISTO-2015 project are contained in this dataset. This dataset includes measurements of O2 and CO2 concentration, with O2 reported as deviations in the O2 /N2 ratio, made by the NCAR Airborne Oxygen Instrument (AO2) on the campaigns during the ARISTO: Airborne Research Instrumentation Testing Opportunity project in 2015. The ARISTO-2015 data collection was performed on the NSF/NCAR C-130. The instrument and data processing are described in detail in Stephens et al. (2021).
