A diagonal volatility basis set to assess the condensation of organic vapors onto particles Open
We present a “diagonal” Volatility Basis Set (dVBS) comparing gas-phase concentrations of oxygenated organic molecules (OOM) to their condensed-phase mass fractions.

Temperature, humidity, and ionisation effect of iodine oxoacid nucleation Open
Raising the ionisation rate (IR) increases the ion concentration, but also amplifies ion losses due to ion–ion recombination, consequently diminishing the formation rate of charged clusters at low HIO 3 concentrations.

Iodine oxoacids enhance nucleation of sulfuric acid particles in the atmosphere Open
The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H 2 SO 4 ), stabilized by ammonia (NH 3 ). However, in marine and polar regions, NH 3 is generally low, and H 2 SO 4 is frequently found together with iodine oxoac…

Molecular Understanding of the Enhancement in Organic Aerosol Mass at High Relative Humidity Open
The mechanistic pathway by which high relative humidity (RH) affects gas-particle partitioning remains poorly understood, although many studies report increased secondary organic aerosol (SOA) yields at high RH. Here, we use real-time, mol…
