Multiply emission factors by distances
Description
Calculate hot exhaust emissions by multiplying emission factors by distances weighted by fleet composition profile.
Usage
multiply_ef(
fleet_composition,
dist,
ef,
aggregate = TRUE,
prefix = NULL,
as_list = TRUE
)
Arguments
fleet_composition |
vector; Fleet composition, which is a distribution of fleet based on frequency. If there is only one, 'fleet_composition' is 1.0. |
dist |
units ('km'); Length of each link in km. |
ef |
list or data.table; Emission factors. |
aggregate |
logical; if TRUE (default) emissions are aggregated by pollutant. |
prefix |
character; Add prefix into emissions names. Missing parameter (default) means empty prefix. |
as_list |
logical. If |
Value
units ('g'); emissions per link.
