These data contain 408 instances of annual model output from JULES/IMOGEN simulations, covering the period between 1850-2100.
Each simulation (which corresponds to one netcdf file) provides annual average of carbon stocks of the land, atmosphere and ocean store required to calculate the anthropogenic fossil fuel emissions as the residual of the yearly changes. Also included are the global warming variables, fractional land-cover, natural wetland extent and methane (CH4) flux and the soil temperature and moisture content for additional analysis.
The spatial coverage is global with spatial resolution of the data is 2.5 degrees latitude, 3.75 degrees longitude.
This dataset is the model output that was used in Comyn-Platt et al (2018) [

These data contain 12 sets (4 model configurations x 3 temperature pathways) of annual model output from JULES driven by 34 different GCM climate patterns as described in the IMOGEN system.
The four model configurations included are:
- 'BLco' - Baseline, or control, configuration without methane feedback.
- 'CH4_lowQ10' - CH4 feedback configuration with a low temperature sensitivity methanogenesis scheme.
- 'CH4_poorFEN' - CH4 feedback configuration with a methanogenesis temperature sensitivity representative of 'poor fen' type wetlands.
- 'CH4_richFEN' - CH4 feedback configuration with a methanogenesis temperature sensitivity representative of 'rich fen' type wetlands.
The three temperature scenarios included are:
- '2deg' - Stabilisation at 2 deg C by 2100 from below
- '1p5deg' - Stabilisation at 1.5 deg C by 2100 from below
- '1p5degOS' - Stabilisation at 1.5 deg C by 2100 following an overshoot to 1.75 deg C
