respeciate

respeciate gives you access to air pollutant emissions profiles in the US/EPA Speciate v5.2 and EU/JRC SPECIEUROPE v2.0 archives via R.

The installation is:

remotes::install_github("atmoschem/respeciate")

The currently packaged SPECIATE and SPECIEUROPE archives are:

library(respeciate)
# packaged archives
rsp_info()

Example

Searching the respeciate (SPECIATE + SPECIEUROPE) for a profile, e.g. using a keyword:

rsp_find_profile("cement")

Limiting the search to just SPECIEUROPE:

rsp_find_profile("cement", source="eu")

Getting the first profile in SPECIEUROPE:

prf <- rsp(1, source="eu")
prf
plot(prf)

Comparing that profile with pm profiles in (US EPA) SPECIATE:

rsp_match_profile(prf, rsp_us_pm(),  
                  output = "plot,summary", 
                  layout=c(5,2))

Notes:

• The nearest match to the SPECIEUROPE EU:1 profile Cement from the US EPA SPECIATE PM subset is SPECIATE US:4377 Cement Kiln.
• In addition, 5/9 of the other nearest matches are cement-related sources.
• The nearest metrics, pd (Pearson's Distance), srd (Spearman Ranked Distance) and sid (Standardized Identity Distance), all tend to zero for better matches. See ?rsp_match_profile in the packaged respeciate documentation for details and references.
