# multi-model, multi-scenario flux data from Liddicoat et al., 2020

---------------------------------------------------
Notes on reproducing the figure from the provided data
---------------------------------------------------
The figure can be recreated by running the python script, TS_C_cycle.py

This requires the Iris package: in addition to standard python packages such as numpy and matplotlib. Links provided in the Related Documents section of this catalogue record:
# SciTools: Open tools for the analysis and visualisation of Earth science data
# iris: A powerful, format-agnostic, community-driven Python package for analysing and visualising Earth science data

This has been tested and runs at:

Python version: 3.6.6
Iris version: 3.0.1

The python script TS_C_cycle.py will read data and recreate the entire multi-panel figure from the data files provided for this figure.

Title

Caption for Figure Box TS.5, 1 from the Technical Summary of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6)

Abstract

Carbon cycle processes and projections. Carbon cycle response to forcings. The figure shows changes in carbon storage in response to elevated CO2 (a, b) and the response to climate warming (c, d). Maps show spatial patterns of changes in carbon uptake during simulations with 1% per year increase in CO2 {section 5.4.5.5}, and zonal mean plots show distribution of carbon changes is dominated by the land (green lines) in the tropics and northern hemisphere and ocean (blue lines) in the southern hemisphere. Hatching indicates regions where fewer than 80% of models agree on the sign of response. (e) Future CO2 projections: projected CO2 concentrations in the SSP scenarios in response to anthropogenic emissions, results from coupled ESMs for SSP5-8.5 and from the MAGICC7 emulator for other scenarios {section 4.3.1}. (f) Future carbon fluxes: projected combined land and ocean fluxes (positive downward) up to 2100 for the SSP scenarios, and extended to 2300 for available scenarios, 5-95% uncertainty plumes shown for SSP1-2.6 and SSP3-7.0 {section 5.4.5.4, 5.4.10}. The numbers near the top show the number of model simulations used. (g) Sink fraction: the fraction of cumulative emissions of CO2 removed by land and ocean sinks. The sink fraction is smaller under conditions of higher emissions. {5.4.5, 5.5.1; Figure 5.27; Figure 4.31; Figure 5.25; Figure 5.30; Figure 5.31}
