The mission of Earth System WG is to establish the Prototype Virtual Center for Research and Interdisciplinary Studies for Earth System Science in Asia-Pacific Region being based on APAN. The key subject is to demonstrate the operation of user-oriented virtual venue for meteorological research and development, in which framework the collaborative system development for numerical weather prediction models, the communication of vast amount of data on a near-real time basis for model validation and operation, and the efficient use of computing resources through the integration of available high performance computing resources will be pioneered under grid-enabled environment.


Establishment of Grid-enabled Meteorological R&D infrastructure by mobilizing available resources under dispersed computing environments for future Earth System development.

General Goal

To provide an integrated, high-end system of computing, data facilities, connectivity, software, services, and instruments that enables all scientists and engineers to work in new ways on advanced research problems that would not otherwise be solved (cited from ESG II, USA).

Specific targets

  • Back-up for Super Computing System at low cost HPC + Cluster + WS/PC = Computational GRID
  • Alternative Development Platform for future NWP Models WRF, Super Ensemble, RCCM with High resolution, etc
  • Resource Sharing with Institutions for Data Assimilation joint development, collaborations, feedback, information sharing most valuable provider/customer for NGIS data through GRID
  • Leading Role in IT applications to Meteorology Network Hub Center at national/regional/global scale e.g. First Gov. Office for GRID, Candidate for GSIC of WMO
  • Great Potential of Contribution to South/North Relationship Joint Regional Earth System Center for Asia-Pacific member countries
