ORCAS Medusa Flask Sampler Kernel Data
https://data.eol.ucar.edu/dataset/490.020

Summary
This dataset contains Medusa Flask Sampler kernel data collected by 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. In order
to compare in situ and flask values, an averaging kernel which takes into
account flow rate and mixing time, tau, at time of sampling is required.

Versions
  0.1
  1.0: Final release data.
  2.0: The AO2 and Medusa data sets have been updated to coincide with the
publication of Stephens et al., Atmospheric Measurement Techniques,
2021. For Medusa O2 data, this has included some additional flask
screening and updates to the Ar/N2 correction. For AO2 O2 data, this has
included more extensive QAQC and filtering updates, revisions to the
time-or-flight and mean offset corrections, and implementation of an
empirical ascent/descent correction, as described in the paper. For both
AO2 and Medusa, the O2 data have been updated for a span correction to
the SIO O2 Scale.
