DSNE Seminar with Birgit Hassler, DLR, Germany

The Earth System Model Evaluation Tool (ESMValTool) has been developed with the aim of taking model evaluation to the next level by facilitating analysis of many different Earth System Model (ESM) components, providing well-documented source code and scientific background of implemented diagnostics and metrics and allowing for traceability and reproducibility of results (provenance). This has been made possible by a lively and growing development community continuously improving the tool. The latest version (v2) of the ESMValTool has been released in August 2020 as a large community effort, and since then several additional smaller releases have followed.

This presentation covers some general information about climate models including the underlying physical principles and their complexity growing with each model generation. The evolution of international model intercomparison projects and the technical and scientific requirements for the individual modeling groups to allow for a consistent interpretation of multi-model results will also be briefly discussed. Finally, it will be demonstrated how tools such as the ESMValTool help with streamlining the evaluation and analysis of model simulations, facilitate dealing with huge amounts of data, and offer easy ways of evaluating new datasets and models (e.g. based on artificial intelligence and machine learning) in a broad yet thorough way.
