The Pallastunturi facility offers a designated air space for research flights with e.g. UAV’s and tethered balloon systems. The airspace is horizontally 7km*7km, with 2km ceiling altitude above ground level. Flying beyond visual line of sight is permitted, making vertical measurements through clouds possible.

Physical access is provided to operate user’s own airborne platforms, or utilizing measurements with the FMI’s UAV- fleet. FMI’s measurements encompass ACTRIS aerosol in situ-, and cloud in situ measurements, as well as meteorological parameters.

Operations are supported by continuous measurements of e.g. surface meteorological conditions, cloud base height, boundary layer height and cloud remote sensing observations. The Sammaltunturi station measurements (565 a.s.l.) can be used as reference to airborne observations.

The opportunity is ideal for research on the vertical distribution of atmospheric composition in the sub-Arctic as well as instrument testing.
