So far, observations of air-mass transformations in the Arctic have mostly been conducted from a fixed local position. Only few aircraft-based samplings of air-mass properties over a limited regional area have been reported. This Eulerian point of view does not permit the observations of air-mass modifying processes along their meridional pathway, which are required for model validations. Therefore, we propose a quasi-Lagrange approach following air-masses to and from the Arctic to observe the air-mass transformation processes during warm air intrusions and cold air outbreaks, whereby we focus on warm air intrusions, which have been observed much less frequently in the past. This quasi-Lagrange approach requires a long-endurance airborne facility, which may carry the necessary equipment for the observations. HALO with its exceptional endurance and high lifting capacity is most suited for these observations.
