comments to ChristianeTextor are highly welcome! see also our discussion



  • Table 1: Concept of construction of new names
  • Table 2: Species
  • Table 3: Proposed names for chemistry and aerosols



Table 1: Concept of construction of new names

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 ?
