In vein: Vehicular Emissions Inventories

Aggregate emissions by lumped groups in chemical mechanism

Description

emis_chem2 aggregates VOC emissions by chemical mechanism and convert grams to mol.

Usage

emis_chem2(df, mech, nx, na.rm = FALSE)

Arguments

df	data.frame with emissions including columns "id" and "pol".
mech	Character, "CB4", "CB05", "S99", "S7","CS7", "S7T", "S11", "S11D","S16C","S18B","RADM2", "RACM2","MOZT1", "CBMZ", "CB05opt2"
nx	Character, colnames for emissions data, for instance "V1", "V2"...
na.rm	Logical, to remove lines with NA from group

Value

data.frame with lumped groups by chemical mechanism.
