Short summary
The formation of SOA from toluene on initially dry and wet AS seeds was compared using an OFR at an RH of 68 %. We found that, as OH exposure increased, the SOA yield and ALW of the initially dry seeds approached those of the initially wet seeds while the wet seeds yielded SOA of a higher degree of oxidation at all exposure levels. Our results suggest that AS dry seeds soon at least partially deliquesce during SOA formation; more studies on the interplay of SOA formation and ALW are warranted.
