27th IUGG General Assembly

Please send in abstracts for your contributions to the following iCACGP sponsored sessions:

M08 - Air Quality in the Changing Anthropocene
Convener: John P. Burrows (Germany)
Co-conveners: James Drummond (Canada), Melita Keywood (Australia)

In a world in which industrialisation is proceeding apace, the world's population has now reached over 7.5 Billion, of which more than half live in cities, air quality has become a very significant health and quality of life issue for many people. It also impacts on climate change.  This symposium invites contributions about measurements, models and mitigation practices for air quality and climate change on all time and space scales. Similarly, contributions of relevance to the evolution of stratospheric ozone in thee changing Anthropocene are welcomed.

M09 - The Arctic in the 21st Century: A Hotbed of Global Change
Conveners: James Drummond (Canada), Paul Kushner (Canada)Description
The Arctic is undergoing climatic change at a much greater rate than the rest of the planet, with potential global consequences.  In addition to natural and anthropogenic driving, economic activity in the Arctic is also increasing which brings new challenges regionally and geopolitically.   Increased understanding of this change requires the best measurements, the best models and the best understanding of the science. Many of the issues involve the interface between the various components of the Earth system (ice, snow, ocean, atmosphere, etc.) and also frequently transcend the traditional disciplinary boundaries. Papers are solicited concerning measurements, models and interpretation with a special emphasis on trans-disciplinary and interface issues affecting the Arctic and relating to Arctic

JM02 - Anthropogenic changes in Chemistry and Physics of the Atmosphere: Evidence and Attribution Studies (IAMAS, IAVCEI, IAG)

Convener: John P. Burrows (Germany, IAMAS)
Co-Conveners: Maria Kanakidou (Greece, IAMAS), Franco Tassi (Italy, IAVCEI), Isabelle Panet (France, IAG)

This symposium focuses on the impact of natural emissions, such as those from volcanoes, and anthropogenic fluxes on atmospheric composition, chemical transformation, dynamics and climate. In this context we welcome contributions from

i) laboratory and chamber studies
ii) field measurements;
iii) satellite observations;
iv) numerical modelling;
v) scientific and socio-economic assessments.
