Temperature, humidity, and ionisation effect of iodine oxoacid nucleation

Andrea Baccarini, Lubna Dada

Iodine oxoacids are recognised for their significant contribution to the formation of new particles in marine and polar atmospheres. Nevertheless, to incorporate the iodine oxoacid nucleation mechanism into global simulations, it is essential to comprehend ...

Iodine oxoacids enhance nucleation of sulfuric acid particles in the atmosphere

Andrea Baccarini, Lubna Dada, Mihnea Surdu

The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4), stabilized by ammonia (NH3). However, in marine and polar regions, NH3 is generally low, and H2SO4 is frequently found together with iodine oxoacids [HIOx, i.e., iodic acid ...

Iodic acid, sulfuric acid and methanesulfonic acid collected during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Measurements of iodic acid, sulfuric acid and methanesulfonic acid concentration in the gas phase obtained with a nitrate chemical ionization mass spectrometer (we used an APi-TOF mass spectrometer produced by Tofwerk AG coupled with a Chemical ionization ...

Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions

Julia Schmale, Andrea Baccarini

In the central Arctic Ocean the formation of clouds and their properties are sensitive to the availability of cloud condensation nuclei (CCN). The vapors responsible for new particle formation (NPF), potentially leading to CCN, have remained unidentified s ...
