The Concordiasi project was undertaken in Antarctica to reduce uncertainties in diverse and complementary fields in Antarctica science. Some of the objectives of the project involved investigations of precipitation to constrain the mass budget over Antarctica and stratospheric ozone depletion. The project was a joint French-United States initiative that started during the International Polar Year (IPY). The project was undertaken over Antarctica during September-November, 2008, December, 2009, and was expected to continue between September-December, 2010. It was undertaken as part of the IPY-The Observing System Research and Predictability Experiment. Participants in the project included scientists from France, the US, Italy, and Australia, along with international organizations such as the European Center for Medium-Range Weather Forecasts (ECMWF).
