Exporting emissions to atmospheric models

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 appropiate format suitable to other models.


To install the CRAN version:


To install the development version:


Some functions:

  • 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 plot for emissions
  • wrf_get: Read variables of emission files
  • wrf_put: Write variables in emission files
  • to_as4wrf: Create WRF-Chem inputs using NCL scrip AS4WRF.ncl.
