Coupling High Resolution Earth System Models Using Advanced Computational Technologies
PI: C. D. Peters-Lidard
NASA/Goddard Space Flight Center (GSFC)
Code 974, Greenbelt, MD 20771
Co-I's: W.-K. Tao, P. R. Houser
The primary objective of the project is to apply advanced computational technologies to the problem of coupling high-resolution (e.g., 1 km, or cloud-scale) Earth system models. Specifically, we propose to combine the emerging technologies of the Earth System Modeling Framework (ESMF) and the Land Information System (LIS; http://lis.gsfc.nasa.gov) to couple complex Earth system model components. The PI and Co-I Houser are currently leading the LIS project, funded by the ESTO/CT ESS Round-3 CAN,
whose TRL3 technologies will be advanced and applied in the current project. The land surface models of the LIS include the Community Land Model (CLM) and the NOAH Land Surface Model. These state-of-the-art land surface models will be coupled to the Weather Research and Forecasting (WRF) model and the Goddard Cumulus Ensemble (GCE) model to enable high-resolution modeling. The technologies to be advanced and applied in this work include 1) support for parallel computing architectures (via MPI on the LIS Beowulf cluster); and 2) support for distributed data access, transport, translation, mining and conversion (via the Grid Analysis and Display System/Distributed Oceanographic Data System (GrADS/DODS) server and the ESMF). Both technologies are currently being demonstrated in the LIS for the problem of uncoupled land surface modeling, and this proposal seeks to further their technological readiness levels by applying them to the problem of high-resolution coupled modeling. These technologies are critical to advance ESE science and prediction goals, in which geographically distributed databases may hold petabytes of Earth system observations needed for high-resolution modeling and data assimilation to understand and predict water, energy, and carbon cycles.
This project is a NASA ESTO AIST NRA-02-OES-04 Selection and is being led by the Hydrological Sciences Branch at NASA Goddard Space Flight Center.
