Ice nucleating particles impact the global climate by altering cloud formation and properties, but the sources of these emissions are not completely characterized. Here, the authors show that secondary organic aerosols formed from the oxidation of or

The presence of ice in mixed-phase clouds has a vital impact on their radiative properties, lifetime, and ability to precipitate. Ice crystal formation is initially induced by a rare subset of ambient aerosol particles called ice-nucleating particles

This study reports on the first set of ambient observations of sub-1.0 hygroscopicity values (i.e., growth factor, ratio of humidified-to-dry diameter, GF=D(p,wet)/D(p,dry) and f(RH), ratio of humidified-to-dry scattering coefficients, less than 1) w

The Aerodyne Aerosol Mass Spectrometer (AMS) is a widely used instrument to quantify the composition of non-refractory submicron aerosol, in particular, organic aerosol (OA). Past comparisons, particularly of aircraft data in continental areas, have

From 2016–2018 a DC-8 aircraft operated by the U.S. National Aeronautics and Space Administration (NASA) made four series of flights, profiling the atmosphere from 150 m to ~ 12 km above sea level from the Arctic to the Antarctic over both th

pH is a fundamental aerosol property that affects ambient particle concentration and composition, linking pH to all aerosol environmental impacts. Here, PM1 and PM2.5 pH are calculated based on data from measurements during the California Research at
