Abstract

The NCAR Airborne Oxygen Instrument (AO2) was mounted onboard the NSF/NCAR GV HIAPER (Gulfstream-V High-performance Instrumented Airborne Platform for Environmental Research) aircraft (Tail Number N677F) during the ORCAS (O2/N2 Ratio and CO2 Airborne Southern Ocean Study) campaign with research flights from Punta Arenas, Chile from 5 January to 29 February 2016. The submitted AO2 data are in 1 flat ascii text file per flight. Each file contains 1 Hz interpolated values (of the original ~ 2.5-second data) matching the times in the RAF data files. The files are in NASA Ames 1001 format, with a final comment line of variable names (UT CO2_AO2orig O2_AO2orig APO_AO2orig CO2_AO2 O2_AO2 APO_AO2), spaces separating columns, and 9999.99 for missing data. The reported times correspond to when the air entered the inlet. This instrument measures O2/N2 ratio as well as CO2 concentration.
