Abstract. Hector, an open-source reduced complexity climate-carbon cycle model. Hector is a computationally efficient source of climate information, capable of completing a run in a fraction of a second. Hector models critical Earth system processes on a global and annual basis. Here we present an updated version of the model, Hector V3. In this manuscript, we document Hector’s new features, and implementation of new science (e.g., radiative forcing calculations, carbon cycle, etc.). Hector V3 results are in good agreement with historical observations of CO2 concentrations and global mean surface temperature, and its future temperature projections are consistent with more complex Earth System Model output data from the Sixth Coupled Model Intercomparison Project. We document that Hector V3 is a flexible, performant, and robust simulator of contemporary and 21st-century global climate, and in closing, discuss future areas of improvement and research with respect to the model’s scientific, stakeholder, and educational priorities.

Short summary
Hector is an easy-to-use global climate-carbon cycle model. With its quick run time Hector can provide climate information from a run in a fraction of a second. Hector models global and annual basis. Here we present an updated version of the model, Hector V3. In this manuscript, we document Hector’s new features. Hector V3 is capable of reproducing historical observations and its future temperature projections are consistent with more complex models.
