Carbon-Climate Box Model

This repository contains a simple process-based box model for Temperature and Carbon, which can reproduce the behaviour of MPIESM-LR-1.2. This box model is based on a number of pre-existing models:

• Box model from Lenton (2000):
  • Land component of carbon box model
  • General idea of ocean carbon box model component
• (L)OSCAR (Zeebe, 2012):
  • Ocean carbon box model component improvements
  • Advection scheme (simplified here)
  • Air-sea CO2 exchange
• FaIR (Leach et al., 2021), version implementation as in FRIDA v1.0
  • CO2 radiation calculation
  • reading in non-CO2 effective radiative forcing computed with FaIR (data from Chris Smith)
• Ocean temperature box model from Li et al. (2020) (similar to that of FaIR)
  • Three layer ocean box model for the temperature model
