How to speciate EDGAR emissions for CBMZ?
I used the R package eixport (Ibarra-Espinosa et al., 2018) to download EDGAR data (5 and spec voc 4.3.2) and then include several speciations for chemical mechanisms according to Carter (2015) and Lopez-Norena et al (2019).
The functions to download EDGAR are commented. This means that you must download all NetCDF files before running chem_edgar.
