The Polar Stratosphere in a Changing Climate (POLSTRACC) - Overview and First Results of the Aircraft Campaign -

The mission "The Polar Stratosphere in a Changing Climate" (POLSTRACC) employs the German High Altitude and Long Range Research Aircraft (HALO) to provide new scientific knowledge on the Arctic lowermost stratosphere and upper troposphere under the present load of ozone depleting substances and greenhouse gases.

The field campaign is divided into three phases for addressing (i) the early polar vortex and its wide-scale vicinity in December 2015 (from Oberpfaffenhofen, Germany), (ii) the mid-winter vortex from January to March 2016 (from Kiruna, Sweden), and (iii) the late dissipating vortex and its wide-scale vicinity in March 2016 (from Kiruna and Oberpfaffenhofen). The mission is supported by a variety of modelling activities, ground based and satellite observations.

The scientific scope of POLSTRACC is broadened by its combination with the SALSA (Seasonality of Air mass transport and origin in the Lowermost Stratosphere using the HALO Aircraft) and GW-LCYCLE (Gravity Wave Life Cycle Experiment, a BMBF/ROMIC project) missions, which address complementary scientific goals sharing the same HALO payload.
In our presentation we will provide an overview of the POLSTRACC mission and present first results of the camapign.
