Mission Statement:To create an integrated, quantitative description of the upper

atmosphere over Antarctica, and its coupling to the global atmosphere and the geospace environment.

Rationale:We do this to resolve open topical questions of earth system science

in which Antarctica occupies a privileged or key position

ObjectivesObjectives1. Interhemispheric science - need to quantify and understand

the similarities and differences• Seasonal effects in electrodynamics, neutral heating, neutral

dynamics, etc.• Dipole offset effects and the role in electrodynamics and

coupling to the atmosphere.• The role of the ionospheric conductivity in conjugacy and

electrodynamics.• The relationship between micro-scale and global-scale

phenomena• Mesosphere and lower thermosphere as the upper boundary to

the neutral atmosphere, and a lower boundary of geospace.2. Inner Magnetospheric Dynamics and its consequences on

the atmosphere3. Global atmospheric electric circuit

• the high latitude effects - conjugacy issues• atmospheric consequences• Schumann Resonances (Antarctic is quietest place on Earth!)

MilestonesMilestones

1. Data portal (2005-2006)1. Define architecture of portal2. Identify all available data sets to address the scientific objectives

(by each working group). 3. Evaluate existing software that could be used for a portal4. Identify central location and implement data portal

2. Identify and implement the necessary tools (in the portal or by individual researchers) to analyze the data collected in the portal

3. Utilize the tools to conduct basic scientific research and complete the list of deliverables

4. Identify lack of instrumentation necessary to address scientific objectives and make recommendation to the community to fill the gaps

5. Apply numerical models based on the understanding gained by milestone 3 to provide an integrated, quantitative description of the upper atmosphere over Antarctica
