1. Characteristics of a successful programme Must address key science question(s) Global relevance Degree of interdisciplinarity, if possible Why now? So what? Who cares? Why Antarctica? Why SCAR? Must make a difference

2. International context Many activities already underway GEM, ILWS, CAWSES, ICS-n, e-STAR, IPY Limited opportunity for new measurements with satellites New starts – Themis, Aeronomy of ice TIMED – another two years Stereo, Solar-B – launch 2005-06 Cluster – December 2005 Polar – September 2005 IMAGE ?? MMS- delayed Ground-based networks never been better Models – now sufficiently mature for assimilation GRID technology now maturing

3. 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

4. Objectives 1. 1.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. 2.Inner Magnetospheric Dynamics and its consequences on the atmosphere 3. 3.Global atmospheric electric circuit the high latitude effects - conjugacy issues atmospheric consequences Schumann Resonances (Antarctic is quietest place on Earth!)

5. Rationale Emergence of new data sets (volume/growth of data sets over last few years)Emergence of new data sets (volume/growth of data sets over last few years) –New Satellite data including IMAGE, POLAR, TIMED –New Magnetometer chains –New SuperDARN radar networks –New Meteor Radars –New Digisonde data Emergence of GRID technologyEmergence of GRID technology –Convergence of Data and Models –Creation of tools to visualize and utilize global data sets Uniqueness of AntarcticUniqueness of Antarctic –Poles are not symmetric (magnetic offsets, etc…) –Land over South pole (I.e. can put instruments there and physics different) Must be an international cooperative effort - Why SCAR?Must be an international cooperative effort - Why SCAR? –Data products are created by international teams and in order to conduct global science need to merge global data sets. –Extension of the Antarctic master data directory. –Links to COMNAP - good forum for coordination. Why is should this science be funded?Why is should this science be funded? –Comprehensive, interhemispheric studies of the atmosphere –Important element of Earth System Science
