Standing Scientific Group on Physical Sciences (SSG-PS)
Within the physical realm, processes at the interfaces between ice, ocean, land and atmosphere are critical to our ability to describe and predict the response to climate change. Outstanding uncertainties will require continued research directed at improving understanding of ice sheet dynamics, extracting climate records from the ice sheet, exploring processes and changes in sea- ice and ocean circulation and improving understanding of atmospheric dynamics and chemistry and the role of the ozone hole in Antarctic climate. A distinct component of physical sciences research in Antarctica is based on the unique properties of the continent that favour its use as a platform for astronomical and solar-terrestrial observations.
SSG-PS is designed to coordinate international scientific research across several fields:
- the Antarctic continent and the Southern Ocean play key roles in global climate change, and observations of climate parameters and their evolution over time there are crucial to understand and predict local and global change.
- Antarctica is a key environment for studies of all aspects of the cryosphere, including deriving the history of climate change from ice cores.
- the position of the magnetic south pole makes Antarctica (like the Arctic in the north) a region where interactions between a variable star, our Sun, and the Earth can be best monitored from the ground.
- the characteristics of the site (dry, cold, and wind free at some locations, especially on the high domes of the polar plateau) make Antarctica one of the places on Earth where astronomical research is expected to be best conducted.
- Lack of human habitation makes Antarctica a pristine environment in which slight contamination from human activities and from distant volcanic eruptions can readily be observed and related to global physical processes.

SCAR Data Policy
The SCAR Data Policy aims to provide a framework for SCAR-related research data to be handled in a consistent manner, and to strike a balance between the rights of investigators and the need for widespread access through the free and unrestricted sharing and exchange of both data and metadata. In order to be considered part of a SCAR Research Programme, each Project should follow this policy:

Scientific Research Programmes within SSG-PS:
- Astronomy and Astrophysics from Antarctica (AAA) - Contact: John Storey (email@example.com)
- Antarctic Climate Change in the 21st Century (AntClim21) (starts January 2013) - Contact: Nancy Bertler (Nancy.Bertler@vuw.ac.nz)
- AntClim21 is a successor to AGCS and incorporates, among other things, two previously free-standing Expert Groups which still operate as separate communities, though integrated with AntClim21:-
- Antarctica and the Global Climate System (AGCS) (co-sponsored by the World Climate Research Programme) - ending 2012
SCAR's AGCS team was asked to take the lead in the preparation of a report on Antarctic Climate Change and the Environment (ACCE), to consider the past and possible future changes in the physical environment of the Antarctic and the impact on the biota. It was published in December 2009. Annual updates are submitted to Antarctic Treaty Consultative Meetings. The report and annual updates are available on the ACCE publication page.

SCOR - Scientific Committee on Oceanic Research, Oceanography Expert Group
In addition to the SCAR/SCOR partnership sponsoring ICED (see above), a joint SCAR/SCOR Oceanograpy Expert Group was set up to focus on physical oceanography, while recognising the inter-dependence of physical, chemical and biological processes in the Southern Ocean. It is co-sponsored with the Life Sciences SSG.
SCOSTEP - Scientific Committee on Solar Terrestrial Physics
- SCOSTEP Website

- SCOSTEP Annual Report for 2009
Annika Seppälä is the SCAR representative on the Bureau of the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP), and provides a key link between SCOSTEP and SCAR programmes, such as ICESTAR (see under Scientific Research Programmes above).
WCRP - World Climate Research Program
The WCRP and SCAR share common goals in seeking to observe, understand, and predict climate variability and change in the Antarctic region, including the Southern Ocean. Through the SCAR-WCRP Memoranda of Understanding, the WCRP and SCAR aim to share corresponding efforts and resources and avoid duplication. This will be achieved through SCAR co-sponsoring the following activities of the WCRP:
(ii) the Climate and Cryosphere Project (CliC), (jointly with IASC and WCRP),
as well as through the WCRP co-sponsoring the new SCAR programme on Antarctica in the Global Climate System (AGCS).
