Buenos Aires, Argentina, 11-14 September 2012

Long-term changes to Earth’s atmosphere are becoming more and more relevant to the future of our world and it is paramount that we quantify and understand changes occurring at all levels within the coupled atmospheric system. The increasing concentration of greenhouse gases, stratospheric ozone depletion, varying solar and geomagnetic activity, secular change of Earth’s magnetic field, and changing dynamics propagating up from the troposphere are some of the possible causes of long-term changes in the stratosphere, mesosphere, thermosphere and ionosphere. The goals of this workshop are to review the current state of knowledge about trends in these atmospheric regions, and to discuss what research is necessary for resolving inconsistencies, reducing uncertainties, and achieving a deeper understanding of middle and upper atmospheric climate change - especially the relative influences of anthropogenic and solar effects.

We welcome papers using all types of observational techniques to determine the long-term changes and trends that have occurred in the past and also to determine the processes behind those changes.

The previous Workshops on Long-Term Changes and Trends in the Atmosphere were: (1) 1999 Pune, India; (2) 2001 Prague, Czech Republic; (3) 2004 Sozopol, Bulgaria; (4) 2006 Sodankyla, Finland; (5) 2008 Saint Petersburg, Russia; (6) 2010 Boulder, Colorado, USA
