cgeniepy: A Python package for analysing cGENIE Earth System Model output

Abstract The cGENIE model is an numerical model that simulates the various components of the Earth system (e.g., atmosphere, ocean, land, biosphere, ice sheet) and their interactions. It has been widely used in studying and reconstructing the past ocean and climate states. Here, I provide a Python package cgeniepy for reading, analysing, and visualising the cGENIE model output, and performing the model-data comparison. The package is designed to facilitate the post-simulation analysis for all cGENIE users. The package is designed as object-oriented, thus many features are standalone and can be used without cGENIE background.
