Summary

Current climate change is mostly the result of increasing atmospheric greenhouse gases concentration, particularly carbon dioxide (CO2). The land has been absorbing about a third of anthropogenic CO2 emissions, but this may change. Earth System Models attempts to predict future climate, accounting for feedbacks, including how the land will respond. The Dual Arrhenius and Michaelis-Menten (DAMM) kinetics model is a semi-mechanistic model of heterotrophic respiration [@Davidson:2012], it estimates respiration as a response to soil temperature and soil moisture. This model can be applied at various scales by empiricists and modelers to better understand respiration.

Statement of need

DAMMmodel is a Julia package providing functions to use, parameterize, and visualize the DAMM model, using the Makie.jl package [@DanischKrumbiegel2021]. The Julia programming language is particularly adequate, as empiricists require simple synthax, and modelers require speed. DAMMmodel may be directly used from Earth System Models as a module, and by empiricists to parameterize the model to their data and visualize the results. It may also be used for teaching. \autoref{fig:example}
