Dear Christiane and Jonathan,
I agree that the proposed names are clear. As a non-expert in
atmospheric chemistry I find it helpful to have the "due_to"
construction to emphasise the difference between primary and secondary
aerosols.
I also agree with Jonathan's suggestion that the primary aerosol name
should include "particulate".
Best wishes,
Alison
