Nomenclature
Nomenclature of the variables
The names of the variables are composed of different abbreviations which are connected by underline characters. The abbreviations are deduced from the English language. To specify a variable, abbreviations (in capital letters) concerning the most important information are ordered as follows:
- Module (only for validation, costs and river loads)
- Emission pathway or kind of variable;
- Parameter, factor or ratio;
- Environmental compartment, ratio or calculation approach;
- Source and
- Substance group or substance
Detailed specifications for the abbreviations are made in lower case letters after the main abbreviation.
Step 1
The first abbreviation in the variable name (step 1) indicates the module which uses the variable. However, it is left out if the variable belongs to a substance emission module, which is why this position is left blank in most cases.
Abbreviations | English term | German term |
RM | river module | Gewässermodul |
VM | validation module | Validierungsmodul |
CM | cost module | Kostenmodul |
Step 2
The following abbreviation (or the first, in case of the substance emission module) represents the category of data or emission pathway (step 2).
