【 摘 要 】

Simple climate models play an integral role in the policy and scientificcommunities. They are used for climate mitigation scenarios within integratedassessment models, complex climate model emulation, and uncertainty analyses.Here we describe Hector v1.0, an open source, object-oriented, simple globalclimate carbon-cycle model. This model runs essentially instantaneously whilestill representing the most critical global-scale earth system processes.Hector has a three-part main carbon cycle: a one-pool atmosphere, land, andocean. The model's terrestrial carbon cycle includes primary production andrespiration fluxes, accommodating arbitrary geographic divisions into, e.g.,ecological biomes or political units. Hector actively solves the inorganiccarbon system in the surface ocean, directly calculating air–sea fluxes ofcarbon and ocean pH. Hector reproduces the global historical trends ofatmospheric [CO₂], radiative forcing, and surface temperatures. Themodel simulates all four Representative Concentration Pathways (RCPs) withequivalent rates of change of key variables over time compared to currentobservations, MAGICC (a well-known simple climate model), and models from the5th Coupled Model Intercomparison Project. Hector's flexibility, open-sourcenature, and modular design will facilitate a broad range of research invarious areas.
