UPLC-MS/MS replication data for secondary organic aerosol formation from early-generation oxidation products of decamethylcyclopentasiloxane depends on seed aerosol composition

Year: 2026

Type: dataset

Abstract: These measurements are part of chamber experiments conducted at the University of Colorado Boulder to investigate secondary organic aerosol (SOA) formation from the early-generation oxidation products of decamethylcyclopentasiloxane (D5) under low OH exposure conditions. The associated data represent gas- and particle-phase samples collected for offline analysis to characterize the distribution of early oxidation products in each ammonium sulfate-seeded experiment, as well as the average across all experiments. Samples were collected over a three-hour period after the lights were turned off, corresponding to a total sampled volume of 3.6 m³, or approximately 18% of the chamber's total volume. Results are reported as signal distributions in percentage.
