Scope
Mass PM2.5 emissions from the bus fleet per year in Helsinki Metropolitan Area (HMA). The variable describes

Definition

Causality

List of parents:

  • Emission factors
  • Bus traffic intensity (number of bus trips? km travelled?)
  • Travelling velocity
  • Temperature (other weather factors? - would this be a weather variable, a temperature variable, or not a variable?)
  • Engine type
  • Fuel type


From paper model

  • Bus km travelled
  • Bus activity
  • Relative emission factors

Data

List of data files or sources:

Formula

Analytica_id:

<anacode>Var a:=bus_km*(emission_factor/1000); a:=a*Relative_emission_fa; a:=a*Relative_emission_f2; a*Rel_bus_activity</anacode>
