5th IAGA/ICMA/CAWSES Workshop "Long-Term Changes and Trends in the Atmosphere:

Increasing concentration of greenhouse gases in the atmosphere, stratospheric ozone depletion, as well as long-term changes of solar and geomagnetic activity can result in long-term changes and trends in the stratosphere, mesosphere, thermosphere and ionosphere. The measurements of atmospheric constituents from space, airborne and ground-based platforms have blossomed in the past two decades and so the atmospheric models.

The main goal of this workshop is to review our current observational and model-simulation knowledge and understanding of trends. The workshop is focused on the determination of long-term trends and changes and the quantification of the role of anthropogenic changes (primarily greenhouse effect) versus Sunґs effects in the observed trends. Model interpretation and prediction of trends of greenhouse origin is of high importance, as well.

Papers dealing with availability and quality of observational data for trend studies, observational determination of long-term changes and trends as well as those dealing with simulations and theoretical studies of trends and long-term changes in the mesosphere, thermosphere and ionosphere as well as in the stratosphere and partly in the troposphere (not main focus of the workshop) are welcome.
