During the first three years of GEMS reports have been written to discuss the validation methods in the different subprojects of GEMS. This document will combine and extend the discussion of scoring approaches provided in these reports. The aims are:
- To rationalize the choice of validation methods in atmospheric chemistry, and to compare them to methods used in numerical weather prediction.
- To “harmonize” the scoring methods: propose a default set of common scores for the different subprojects.
- To suggest common graphical formats of the scoring results and presentation on the GEMS website.
- To define one (or a few) key score(s) which can document the improvement over time of the GEMS system.
It is acknowledged that the application of the recommendations that are derived from this report may remain limited within the GEMS project. On the other hand, this could form a basis in the follow-up of GEMS, the MACC project. Here, the integration of the different modules
