Table 1: Concept of construction of new names[edit | edit source]
Table 1 provides the basic ideas of a concept for the construction of standard_names for aerosols and chemistry. The ideas in table 1 are mainly based on the PRISM project (Peter van Velthoven) see PRISM Standard Name Tables, latest Version, V 1.3
Remarks
- all forcing variables are still missing
- articles and prepositions should be avoided
- allways give atmosphere/ocean/soil?
- try to use SI units (e.g. not hours but seconds)
- how to distinguish ion - radicals, e.g. NO3 ?
