Emission Inventory for Air Pollutants

Emission Inventory Method
9
E = Energy × EF × FCF where: E:emission of pollutants (g) Energy:energy input (kW‧h) EF:emission factor (g/kW‧h) FCF:fuel modification factor
Energy = MCR × LF × Act where: MCR:maximum power of engine (kW) LF:loading factor Act:activity (hr)
LF = ( AS / MS )3
where: AS:actual ship speed (knot) MS:maximum ship speed (knot)

Future Works
1.To include more real-time activities of mobile sources into
real-time forecasting system;
2. To evaluate the impacts of ship
activities covered by AIS around
Taiwan on primary and secondary
air pollutants, like fine particle and
ozone, by three-dimensional air
quality model CMAQ;
3. To develop the real-time air quality
forecasting system for the whole Chinese Taipei by CMAQ. 21
