fair 1.1.2

Python package to perform calculations with the FAIR simple climate model

[](https://travis-ci.org/OMS-NetZero/FAIR)

# FAIR Finite Amplitude Impulse-Response simple climate-carbon-cycle model

## Installation 1. Make sure you have Python 2 and pip installed and are working in an environment that uses Python 2 by default 1. From terminal/command prompt pip install fair

## Usage FAIR takes emissions of greenhouse gases, aerosol and ozone precursors, and converts these into greenhouse gas concentrations, radiative forcing and temperature change.

There are two ways to run FAIR: 1. Carbon dioxide emissions only with all other radiative forcings specified externally (same behaviour as FAIR 1.0 with the same keyword arguments); 1. All species included in the RCP emissions datasets, with, optionally, solar and volcanic forcing still specified externally. For convenience, the RCP datasets are provided in the RCP subdirectory and can be imported:

` from fair.RCPs import rcp85 emissions = rcp85.Emissions.emissions `

For further information, see the example ipython notebook contained in the GitHub repo at https://github.com/OMS-NetZero/FAIR.
