emis_wrf-deprecated

Gridded emissions, which can be a SpatialPolygonsDataFrame, or a list
of SpatialPolygonsDataFrame, or a sf object of "POLYGON". The user must enter
a list with 36 SpatialPolygonsDataFrame with emissions for the mechanism CBMZ.

Number of repetitions of the emissions period

String indicating Day Month Year Hour and Minute in the format
"d-m-Y H:M" e.g.: "01-05-2014 00:00" It represents the time of the first
hour of emissions in Local Time

Time zone as required in for function <code><a rd-options="" href="/link/as.POSIXct?package=vein&version=0.7.8" data-mini-rdoc="vein::as.POSIXct">as.POSIXct</a></code>

Coordinate reference system, e.g: "+init=epsg:4326". Used to
transform the coordinates of the output

logical value to indicate if sdf is a list or not

<code>emis_wrf</code> returns a dataframes with columns lat, long, id, pollutants, local time
and GMT time. This dataframe has the proper format to be used with WRF
assimilation system: "ASimilation System 4 WRF (AS4WRF Vera-Vala et al (2016))

Elaboration of vehicular emissions inventories,
consisting in four stages, pre-processing activity data, preparing
emissions factors, estimating the emissions and post-processing of emissions
in maps and databases. More details in Ibarra-Espinosa et al (2018) <doi:10.5194/gmd-11-2209-2018>.
Before using VEIN you need to know the vehicular composition of your study area, in other words,
the combination of of type of vehicles, size and fuel of the fleet. Then, it is recommended to
start with the function inventory to create a structure of directories and template scripts.
