Plain Language Summary: The age of air is a transport characteristic of the stratospheric general circulation. Vertical profile of the age of air estimated from cryogenic air samples taken over Biak, Indonesia is investigated by applying the boundary impulse evolving response (BIER) method and Lagrangian backward trajectories to the transport field simulated by a general circulation model nudged to reanalysis.
