Horizontal (left) and vertical (right) distribution of airborne flask sample locations identified as being of stratospheric origin. Thin dashed black lines on the map illustrate the flight tracks of all 9 campaigns of the 3 airborne projects. Symbols indicate the campaigns during which the stratospheric samples were collected, and colors show the potential temperature at which the sample was taken.
