This is the repository for Hector, an open source, object-oriented, simple global climate carbon-cycle model. It runs essentially instantaneously while still representing the most critical global scale earth system processes, and is one of a class of models heavily used for for emulating complex climate models and uncertainty analyses. For example, Hector's global temperature rise for the RCP 8.5 scenario, compared to observations and other model results, looks like this:
The primary source of Hector model documentation is the Github wiki. Please note that the wiki documents are included in the repository as a git submodule. To clone the repository as well as the documentation, you can use git clone --recursive. If you have already cloned non-recursively, you can fetch (download) the documentation by running git submodule init; git submodule update. The code is also well documented with Doxygen-style comments. A formal model description paper (Hartin et al. 2015) documents its science internals and performance relative to observed data, the CMIP5 archive, and the reduced-complexity MAGICC model.
