In vein: Vehicular Emissions Inventories

Speciation of emissions

Description

speciate separates emissions in different compounds. It covers black carbon and organic matter from particulate matter. Soon it will be added more speciations

Usage

speciate(
  x = 1,
  spec = "bcom",
  veh,
  fuel,
  eu,
  list = FALSE,
  pmpar,
  verbose = FALSE
)

Arguments

x	Emissions estimation
spec	The speciations are: "bcom": Splits PM2.5 in black carbon and organic matter. "tyre" or "tire": Splits PM in PM10, PM2.5, PM1 and PM0.1. "brake": Splits PM in PM10, PM2.5, PM1 and PM0.1. "road": Splits PM in PM10 and PM2.5. "nox": Splits NOx in NO and NO2. "nmhc": Splits NMHC in compounds, see ef_ldv_speed. "voc": Splits NMHC in voc groups according EDGAR. "pmiag", "pmneu", "pmneu2", "pm2023": Splits PM in groups, see note below.
veh	Type of vehicle: "bcom": veh can be "PC", "LCV", HDV" or "Motorcycle". "tyre" or "tire": not necessary. "brake": not necessary. "road": not necessary. "nox": veh can be "PC", "LCV", HDV" or "Motorcycle". "nmhc":see below ""pmiag", "pmneu", "pmneu2", "pm2023": not necessary.
fuel	Fuel. "bcom": "G" or "D". "tyre" or "tire": not necessary. "brake": not necessary. "road": not necessary. "nox": "G", "D", "LPG", "E85" or "CNG". "nmhc":see below "pmiag", "pmneu", "pmneu2", "pm2023": not necessary.
eu	Emission standard "bcom": "G" or "D". "tyre" or "tire": not necessary. "brake": not necessary. "road": not necessary. "nox": "G", "D", "LPG", "E85" or "CNG". "nmhc":see below "pmiag", "pmneu", "pmneu2", "pm2023": not necessary.
list	when TRUE returns a list with number of elements of the list as the number species of pollutants
pmpar	Numeric vector for PM speciation eg: c(e_so4i = 0.0077, e_so4j = 0.0623, e_no3i = 0.00247, e_no3j = 0.01053, e_pm25i = 0.1, e_pm25j = 0.3, e_orgi = 0.0304, e_orgj = 0.1296, e_eci = 0.056, e_ecj = 0.024, h2o = 0.277) These are default values. however, when this argument is present, new values are used.
verbose	Logical to show more information

Value

dataframe of speciation in grams or mols

after eu = OM, all profiles are Chinese # the following specs will be removed soon

• "iag_racm": ethanol emissions added in hc3.

• "iag" or "iag_cb05": Splits NMHC by CB05 (WRF exb05_opt1) group .

• "petroiag_cb05": Splits NMHC by CB05 (WRF exb05_opt1) group .

• "iag_cb05v2": Splits NMHC by CB05 (WRF exb05_opt2) group .

• "neu_cb05": Splits NMHC by CB05 (WRF exb05_opt2) group alternative.

• "petroiag_cb05v2": Splits NMHC by CB05 (WRF exb05_opt2) group alternative.

spec "pmiag" speciate pm2.5 into e_so4i, e_so4j, e_no3i, e_no3j, e_mp2.5i, e_mp2.5j, e_orgi, e_orgj, e_eci, e_ecj and h2o.

specs: "neu_cb05", "pmneu" and "pmneu2" provided by Daniel Schuch, from Northeastern University. "pm2023" provided by Iara da Silva; Leila D. Martins

Speciation with fuels "E25", "E100" and "B5" made by Prof. Leila Martins (UTFPR), represents BRAZILIAN fuel

pmiag2 pass the mass only on j fraction

spec "voc" splits nmhc into the 25 VOC groups according: Huang et al 2019, "Speciation of anthropogenic emissions of non-methane volatile organic compounds: a global gridded data set for 1970-2012" ACP. Speciation In development.
