Presentation of the Concordiasi project



Concordiasi is an international project, currently supported by the following agencies: Météo-France, CNES, IPEV, PNRA, CNRS/INSU, NSF, NCAR, Concordia consortium, University of Wyoming, Purdue University and University of Colorado. ECMWF also contributes to the project through computer resources and support, and scientific expertise. Concordiasi is part of the THORPEX-IPY cluster within the International Polar Year effort.

Two field experiments are part of Concordiasi, one which has occurred during the autumn 2008 (Austral spring) in Antarctica and a second one planned in Austral spring 2010.
Additional in-situ measurements include radiosoundings at the Concordia station at Dome C and at Dumont d'Urville in 2008 and high altitude balloons able to drop dropsondes, launched on demand under a parachute and measuring atmospheric parameters on their way down over Antarctica in 2010.
Data can be accessed at the following address http://www.cnrm.meteo.fr/concordiasi-dataset/

Numerical simulations will use the field experiment data. The main goal is to provide validation data to improve the usage of polar-orbiting satellite data over Antarctica, in particular IASI radiances.
On board the European satellite MetOp-A launched in October 2006, IASI is a sounder instrument measuring the infrared spectrum with an improved accuracy for temperature and humidity sounding in the troposphere and stratosphere. The other areas of interest are the fine scale meteorological and climatic studies of the Antarctic plateau, the study of the influence of better polar area predictions over lower latitudes and over the ozone simulation, together with the monitoring of the polar vortex at the end of winter, thanks to additional stratospheric measurements. Working towards these goals will contribute to establish a sustainable observing system for climate over Antarctica, taking into account the potential of advanced sounders such as IASI.
