1 Who is? Tasmanian Partnership for Advanced Computing Partner in ARCS (Australian Research Collaboration Services Strengths, Earth Systems Science, Compute and storage facilities Located at University of Tasmania, Hobart Partnership between: University of Tasmania CSIRO Marine Atmos. Res. Australian Antarctic Division Bureau of Met. Research Centre Antarctic Climate & Ecosystems CRC ARC Network Earth Systems Science

2 Mean Model Climate models, and climate model credibility Observations

3 Projections of Future Changes in Climate Best estimate for low scenario (B1) is 1.8 C (likely range is 1.1 C to 2.9 C), and for high scenario (A1FI) is 4.0 C (likely range is 2.4 C to 6.4 C). Broadly consistent with span quoted for SRES in TAR, but not directly comparable

4 Projections of Future Changes in Climate Figure SPM-6, TS-30, 10.9 Perth Precipitation increases are very likely in high latitudes in Decreases are likely in most subtropical land regions in

5 Future Climate: Greenland Ice Sheets =1.4m Ice Sheets: a key risk for future climate

6 Total Greenland ice sheet melt area increased on average by 20% from 1979 to On the western part of the ice sheet the melt area increased by 30% The increasing trend in the total area of melting bare ice is unmistakable at 13% per year

(2007) West Antarctic ice sheet (7 m SLE) grounded below sea level on marine sediment experiencing high geothermal heat flow.

11 Documentation Global Search 51 Categories uses Over the last two years Enabled for THREDDS related services, scripting

12 Current relevant project Rolling out THREDDS network (for Earth Systems Science) OpenDAP, WCS, gridftp, http and ftp Metadata discovery search engine (with administration) Adoption by Alexandria Digital Library AO DAAC (IMOS 5.12) (with enhanced capabilities) Web Map Services Plugin for LAS (adopted by LAS) Client portal in gridsphere WMS functionality in THREDDS (with UK) A workflow for reading OpenDAP repositories (or catalogs) and augmenting the metadata to be conformal with marine profile

13 Near term appropriate projects Problem Research products in time, and transparently Solution Model simulations OZ-US Re-analyses (GODAE, ECCO, GECCO, SODA, BlueLINK 2) US PCMDI updates and preservation (~31 Terrabytes, 23 model, 16 nations) Trial data US_OZ file virtualisation, PCMDI to ANU with OpeNDAP Or a portal with catalogue, select PCMDI not cached in Australian, and copy to Australia
