Introduction<br />

While meteorology was the major focus of the first<br />

IPY (1882–1883), in the IPY <strong>2007–2008</strong> only 17 from<br />

the 170 officially endorsed scientific projects were<br />

assigned to the domain of “atmosphere”. This does not<br />

mean, however, that the role of atmospheric research<br />

in polar sciences is not as high as it used to be. The<br />

modern atmospheric science has become inherently<br />

multi-disciplinary and there is a very significant<br />

“atmospheric dimension” in IPY projects carried out<br />

in all IPY domains such as ice, ocean, land, people<br />

and others. Many of the critically important changes<br />

in the Earth system are occurring in the atmosphere<br />

,including the buildup of greenhouse gases with<br />

corresponding increase of temperatures, evolving<br />

statistical structure of precipitation and stratospheric<br />

ozone depletion - to name just a few.<br />

The 17 IPY projects assigned to the domain of<br />

“Atmosphere” are listed in Table 2.1-1.<br />

We present here an overview of the preliminary<br />

results of polar atmosphere studies obtained in the<br />

course of implementation of some the above projects.<br />

They are grouped into two main topics: (1) physics<br />

of the atmosphere, climate change and processes in<br />

the stratosphere and (2) tropospheric chemistry, air<br />

pollution and climate impacts.<br />
