This project – which involves scientists from two dozen countries – will examine how atmospheric processes in the Southern Hemisphere affect current climate, and provide an important baseline for assessing future climate change. COMPASS will obtain the first circumpolar snapshot of the Southern Hemisphere atmospheric environment – covering physical, chemical and ecological properties – a major observational milestone. Only by harnessing the resources of the global polar community can this multinational project achieve the depth of investigation required to improve knowledge of future climate change and its impacts.

Antarctica is the primary heat sink in the global climate system: it plays an important role in climate change and variability, and Antarctic atmospheric processes affect the rest of the planet via the atmosphere and the sea. Using satellites and the state-of-the-art HIAPER research aircraft, AC Squared will help scientists gain a better understanding of how these processes work – knowledge that is essential if we are to develop models that more accurately predict global climate change.

The proposed activity aims at establishing a bipolar network to obtain data needed to quantify properties of aerosols at high latitudes, including seasonal background concentrations by measurements of aerosol optical depth (AOD), spectral characterizations, and the evolutionary patterns of the natural and anthropogenic processes that perturb the aerosol cycles. An effort to quantify direct and indirect climate forcing by polar aerosols will be made through a set of closure experiments using observations in conjunction with model calculation and satellite data.

Global Toxic Pollution, Arctic Contamination - Making the Link
Persistent organic pollutants (POPs) and mercury are toxic chemicals carried by air and water to the Arctic. There, they accumulate in wildlife, as well as in northern people who eat traditional foods. This project will gather information on:
·the source of these pollutants,
·how climate affects where they end up; and
·impacts on northern ecosystems and people.

POLar study using Aircraft, Remote sensing, surface measurements and modelling of Climate, chemistry, Aerosols and Transport (POLARCAT) "Aerosols have a large effect on radiation transmission in the Arctic troposphere, both directly and indirectly via clouds. POLARCAT will study transport to the Arctic of aerosols, as well as of air pollution more generally, from anthropogenic sources and boreal forest fires. It will address the effects of this pollution on atmospheric chemistry and climate. POLARCAT will use a large number of aircraft, a ship, a train, surface stations, as well as satellite data and numerical models. The first campaign, from 26 March - 19 April will use two aircraft based in Longyearbyen, Spitsbergen. Other campaigns in February 2008 and summer 2008 will follow with aircraft being based at various locations throughout the Arctic and in the boreal region."
