Abstract

Concordiasi was a multidisciplinary effort jointly operated by France and the US to study the lower stratosphere and troposphere above Antarctica and the land surface of the Antarctic continent. Concordiasi field experiments were conducted in austral springs 2008, 2009, and 2010, including surface measurements and radiosoundings at the Concordia Antarctica station at Dome C and radio-soundings at the Dumont d'Urville and Rothera sites on Antarctica. An innovative constellation of balloons provided a unique set of measurements covering both volume and time in 2010. The balloon flotilla formed a regional observatory of the atmosphere, which provided in situ measurements inside the winter stratospheric polar vortex and allowed the performance of several soundings of the troposphere. The in situ measurements included position, temperature, pressure, ozone, and aerosol particles, along with profiles below the balloon-borne gondolas.
