If you install the spice with the addon EvaSuite, then you can do two things:
- Compare your simulation experiment with the well-known EObs dataset (Version 23, other versions or datasets needs your adaptation).
- Compare your simulation experiment and a reference simulation with EObs.
The hereon-evasuite is a stand-alone evaluation program (Evasuite-gitlab-dkrz). In the spice-package we tried to integrate automatically the process of installation, configuration and execution. This is a hard task and might be somewhat flawed in some places.
General notes for evaluation with the eva-suite addon
The period for comparison must be within the total period of the available EOBS data set (1950 onwards). Please, keep in mind that the quality of the reference data is not the same over the whole domain and over all decades. The chosen evaluation period should cover at least one year.
The use of eva-suite in the runtime-environment of spice is optional and can be switched off by setting ITYPE_EVAL=0 in the experimental settings ${EXPDIR}/scripts_eva-suite/eva-suite_settings file.
If you want to consider additional observational datasets or more model simulations, you should consider to work with a stand-alone environment of the hereon-evasuite.
Results of mean sea level pressure, two meter temperature and its maximum and minimum, total precipitation and global radiation are visualised as bias, frequency distribution, added value and qq plots under the directory ${SPDIR}/chain/work/${EXPID}/eva-suite/graphics.
