Short summary
AirCore samplers are increasingly deployed to weather balloons to collect continuous atmospheric samples. We introduce a technique that can be used in situ to evaluate different data processing methods that are required to derive vertical trace gas profiles from AirCore measurements after sample recovery. Results from two test flights with a specific AirCore configuration provide evidence for systematic deviations in altitude attribution for the upper levels, which can be empirically corrected.
