This is the repository for Hector, an open source, object-oriented, simple global climate carbon-cycle model that runs very quickly while still representing the most critical global scale earth system processes. Hector is a simple climate model (SCM, also known as a reduced-complexity climate model), a class of models that are extremely versatile with a wide range of applications. Due to their computational efficiency, SCMs can easily be coupled to other models and used to design scenarios, emulate more complex climate models, and conduct uncertainty analyses.

Hector’s output for global mean air temperature change for eight Shared Socioeconomic Pathways (SSPs).

## Installation

The hector R package can be installed using the remotes::install_github function. More detailed installation instructions, including how to set up Hector as a command line executable, can be found here.

remotes::install_github('jgcri/hector')
library(hector)

## Tools and Software That Work with Hector

• GCAM: Hector can be used as the climate component in GCAM
• pyhector: a Python interface to Hector
• fldgen: a spatially resolved temperature & precipitation emulator for CMIP5 ESMs
• HectorUI: run Hector in a web interface!
