In ibarraespinosa/eixport: Export Emissions to Atmospheric Models

eixport

Exporting emissions to atmospheric models, eixport: 0.6.0

Emissions are mass that affects atmosphere in complex ways, not only physical, but also, in the health of humans, ecosystems, economically, etc.

There are several models whose inputs are emissions, such as R-Line or WRF-Chem. This R-Package provide functions to read emissions from VEIN and from other models in different formats and export the emissions into the appropriate format suitable to other models.

Install

To install the CRAN version:

install.packages("eixport")

To install the development version:

devtools::install_github("atmoschem/eixport")

Some functions:

• get_edgar: Download EDGAR emissions data.
• to_rline: Export emissions to other formats
• to_wrf: Combine total/spatial/temporal/split and write emission to file
• to_brams_spm: inputs for SPM BRAMS
• wrf_profile: Create spatial profile for WRF-Chem
• wrf_create: Create emission files to the WRF-Chem
• wrf_plot: simple but useful plot
• wrf_get: Read variables
• wrf_put: Write variables
• to_as4wrf: Create WRF-Chem inputs using NCL scrip AS4WRF.ncl.
• to_munich: To generate inputs for MUNICH model.

Summary

library(eixport)
#> The legacy packages maptools, rgdal, and rgeos, underpinning the sp package,
#> which was just loaded, will retire in October 2023.
#> Please refer to R-spatial evolution reports for details, especially
#> https://r-spatial.org/r/2023/05/15/evolution4.html.
#> It may be desirable to make the sf package available;
#> package maintainers should consider adding sf to Suggests:.
#> The sp package is now running under evolution status 2
#>      (status 2 uses the sf package in place of rgdal)
