| Zusammenfassung |
| Simple climate models play an integral role in the policy and scientific
communities. They are used for climate mitigation scenarios within integrated
assessment models, complex climate model emulation, and uncertainty analyses.
Here we describe Hector v1.0, an open source, object-oriented, simple global
climate carbon-cycle model. This model runs essentially instantaneously while
still representing the most critical global-scale earth system processes.
Hector has a three-part main carbon cycle: a one-pool atmosphere, land, and
ocean. The model's terrestrial carbon cycle includes primary production and
respiration fluxes, accommodating arbitrary geographic divisions into, e.g.,
ecological biomes or political units. Hector actively solves the inorganic
carbon system in the surface ocean, directly calculating air–sea fluxes of
carbon and ocean pH. Hector reproduces the global historical trends of
atmospheric [CO2], radiative forcing, and surface temperatures. The
model simulates all four Representative Concentration Pathways (RCPs) with
equivalent rates of change of key variables over time compared to current
observations, MAGICC (a well-known simple climate model), and models from the
5th Coupled Model Intercomparison Project. Hector's flexibility, open-source
nature, and modular design will facilitate a broad range of research in
various areas. |
