Vehicular Emissions INventories (VEIN)

<figure> <img src="https://user-images.githubusercontent.com/27447280/234115392-b1c891ff-474d-40a3-b9a7-e816ded9bc70.gif" alt="vein" /> <figcaption aria-hidden="true">vein</figcaption> </figure>

TODO

• Include speed functions with Fortran
• Add EF from HBEFA?
• See issues GitHub
• Second edition of my book

System requirements

vein imports functions from spatial packages listed below. In order to install these packages, firstly the user must install the requirements mentioned here.

Installation

CRAN

VEIN can be installed via CRAN or github

install.packages("vein")

GitHub

remotes::install_github("atmoschem/vein")

or if you have a 32 bits machine

install_github("atmoschem/vein",
INSTALL_opts = "--no-multiarch")

---

Run with a project

Use the function get_project and read the documentation, there you can see more projects as well.

library(vein)

awesome_city <- tempdir()
awesome_city
#> [1] "/tmp/RtmpIMx9it"
get_project(directory = awesome_city,
case = "brazil_bu_chem")
#> Your directory is in /tmp/RtmpIMx9it

system(paste0("tree ", awesome_city))

You have to open the file main.Rproj with Rstudio and then open and run main.R

To run main.R you will need these extra packages:

• ggplot2
• readxl
• eixport (If you plan to generate WRF Chem emissions file)

If you do not have them already, you can install:

install.packages(c("ggplot2", "readxl", "eixport"))

Note for non-english and anaconda users

Sometimes you need to install R and all dependencies and a way for doing that is using anaconda. Well, as my system is in portuguese, after installing R using anaconda it changed the decimal character to ‘,’. In order to change it back to english meaning decimal separator as ‘.’, I added this variable into the .bashrc

nano ~/.bashrc
export Lang=C
