ShipEF.Rd
The ShipEF package by the U.S. Environmental Protection Agency provides
functions for assigning emission factors to commercial marine vessels (CMV).
For various pollutants, emission factors depend on vessel characteristics,
vessel operating modes, and/or vessel location. This package can be used in
conjunction with ship power estimates (see the ShipPowerModel
package)
and ship activity data to estimate CMV air emissions.
Each pollutant included in this package has its own function to determine the appropriate emissions factor. There is also a low load adjustment factor, which applies to the emission factors for each pollutant in certain operating conditions.
calcEF_CO
- Carbon monoxide emissions factor
calcEF_CO2
- Carbon dioxide emissions factor
calcEF_HC
- Hydrocarbons emissions factor
calcEF_NOx
- Oxides of nitrogen emissions factor
calcEF_PM
- Particulate matter emissions factor
calcEF_SO2
- Sulfur dioxide emissions factor
calcLLAF
- Low load adjustment factor
calcEF
- Calculates emission factors for all pollutants
and applies the LLAF
