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 link to Hector model documentation is the online manual, which is included in the repository in the vignettes/manual directory.
The code is also 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 (as of version 1.0). In addition, we have developed two package vignettes demonstrating the basics of the Hector R interface and an example application of solving for an emissions pathway.
