EvaSuite: A Framework for Model Evaluation and Verification Using Observational and Model Datasets

Evaluation Suite (EvaSuite) is a modular software framework for the standardised evaluation of regional climate model (RCM) simulations against observational and reference datasets, including model sensitivity analysis. It is designed for high-performance computing platforms and addresses the need for transparent, reproducible, and flexible evaluation workflows for RCMs. EvaSuite combines data harmonisation, spatial and temporal remapping, statistical evaluation, and visualisation within a unified configurable workflow. The framework requires only minimal constraints on input datasets, which can be provided in NetCDF format and identifiable spatial and temporal coordinates, and integrates established climate data processing tools with Python-based modules and a modular extension concept, enabling scalable and customisable analyses. EvaSuite is an open-source evaluation framework maintained by the Climate Limited-area Modelling Community (CLM-Community). It supports systematic reuse across different models, variables, and spatial domains, facilitating consistent evaluation of model performance, including the assessment of model tuning within regional climate modelling.
