A New Approach for In Situ Analysis in Fully Coupled Earth System Models

Workshop: A New Approach for In Situ Analysis in Fully Coupled Earth System Models

Abstract: This work focuses on enabling the use of existing in situ analysis and visualization methods within the model coupling framework, which is specifically designed software layer to combine physical components of Earth system (i.e., atmosphere, ocean) through a standardized calling interface to simplify common tasks such as interpolation among different numerical grids and synchronization of the model components. The new approach enables simultaneous analysis of the vast amount of data produced by multi-component Earth system model in an integrated way and facilitate efficient, interoperable and optimized data analysis and visualization workflows for Earth system science applications. To demonstrate the flexibility and the capability of the new approach, a fully coupled regional atmosphere-ocean modeling application, that aims to investigate air-sea interaction in a very high spatial and temporal resolution have been implemented. In the use case application, both the simulation and in situ visualization application run in parallel on a large-scale HPC platform with both software and hardware rendering support through the use of accelerators.
