Short summary
The AirCore collects a continuous air sample in a long tube that can be read later when the captured air is slowly pushed through an analyzer. Much of the variation of gas composition encountered during collection is preserved, like having up to ~ 100 separate air samples. This is illustrated through examples of actual flights, and the analysis algorithm is described. The AirCore provides access to air as high as the mid stratosphere, enabling validation for satellite air composition soundings.
