MESMER: spatially resolved Earth System Model emulations

--------------------------------------------------------

**MESMER** is a **M**\ odular **E**\ arth **S**\ ystem **M**\ odel **E**\ mulator with

spatially **R**\ esolved output, which stochastically creates Earth System

Model-specific spatio-temporally correlated climate variable field realizations at a

negligible computational cost.



In combination with a global mean temperature emulator, MESMER can account for all three

major sources of climate change projection uncertainty at the local scale: (i) internal

variability uncertainty, i.e., unforced natural climate variability; (ii) forced climate

response uncertainty, i.e., the Earth’s system response to forced natural changes (solar

and volcanic) and human influences (greenhouse gas and aerosol emissions, land use

changes etc.); and (iii) emission uncertainty, i.e., uncertainty in the emission pathway

humans decide to follow. An interface between MESMER and global mean temperature

emulators can be found at https://github.com/MESMER-group/mesmer-openscmrunner.



MESMER is under active development both scientifically and technically. Future work will

increase its user friendliness and extend its emulation capabilities to include

additional emulation methods and target climate variables.

global mean emulator, the following publication should additionally be cited:
