You do not have permission to edit this page, for the following reason:

The action you have requested is limited to users in the group: Administrators.

Explanation: Only annotate your own output variables and parameters. Corresponding variables are grouped, e.g. 'CO2, other GHG, CO, NMVOC emissions', to keep the collection surveyable. Types of variables are explained at the bottom of this form.

The user support system will also use the variable page as information page. So try to describe the variable from a model perspective. You can put an extensive description in the free text if necessary.

The addition (grid) should be placed after the name when the variable is grid based .

Reference:

Variables are classified in drivers, model variables, model variables, model (end-indicator), parameters, external model variables and historical datas.

  • Drivers are external model variables that are used for the core models and have a considerable influence on scenarios.
  • Model variables are variables that are calculated by a model or impact component and are used as input for another model component.
  • Model variables, end-indicator are variables that are calculated by a model or impact component and are final output.
  • External parameters originate from external models, databases, or other sources.They are mostly used as input for one model component.
  • Historical variables are variables that are historical, such as 'Wet days'.
