ef_china
returns emission factors as vector or data.frames.
The emission factors comes from the chinese emission guidelines (v3) from the
Chinese Ministry of Ecology and Environment

v |
Character; category vehicle: "PV" for Passenger Vehicles or 'Trucks" |
t |
Character; sub-category of of vehicle: PV Gasoline: "Mini", "Small","Medium", "Large", "Taxi", "Motorcycles", "Moped", PV Diesel: "Mediumbus", "Largebus", "3-Wheel". Trucks: "Mini", "Light" , "Medium", "Heavy" |
f |
Character;fuel: "G", "D", "CNG", "ALL" |
standard |
Character or data.frame; "PRE", "I", "II", "III", "IV", "V". When it is a data.frame, it each row is a different region and ta, humidity, altitud, speed, sulphur and load_factor lengths have the same as the number of rows. |
p |
Character; pollutant: "CO", "NOx","HC", "PM", "Evaporative_driving" or "Evaporative_parking" |
k |
Numeric; multiplication factor |
ta |
Numeric; temperature of ambient in celcius degrees. When standard is a data.frame, the length must be equal to the number of rows of standard. |
humidity |
Numeric; relative humidity. When standard is a data.frame, the length must be equal to the number of rows of standard. |
altitude |
Numeric; altitude in meters. When standard is a data.frame, the length must be equal to the number of rows of standard. |
speed |
Numeric; altitude in km/h When standard is a data.frame, the length must be equal to the number of rows of standard. |
baseyear_det |
Integer; any of 2014, 2015, 2016, 2017, 2018 |
sulphur |
Numeric; sulphur in ppm. When standard is a data.frame, the length must be equal to the number of rows of standard. |
load_factor |
Numeric; When standard is a data.frame, the length must be equal to the number of rows of standard. |
details |
Logical; When TRUE, it shows a description of the vehicle in chinese and english. Only when length standard is 1. |
correction_only |
Logical; When TRUE, return only correction factors. |
