This paper describes a five-dimensional parameterization of ion-induced nucleation (IIN) that covers the complete range of conditions relevant to the lower atmosphere. The parameters are (1) temperature T (190-300 K), (2) relative humidity RH (0.05-0.95), (3) number concentration of H 2 SO 4 (10 5 -10 8 cm À3 ), (4) first-order loss of H 2 SO 4 to particles (0.00009-0.0245 s À1 ), and (5) ion source rate (2-50 ion pairs cm À3 s À1 ). The parameterization is based on a steady state version of the kinetic a…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
