Abstract The effect of aerosols on the properties clouds is a large source uncertainty in predictions weather and climate. These aerosol‐cloud interactions depend critically ability aerosol particles to form cloud droplets. A challenge modeling representation between turbulence microphysics. Turbulent mixing leads small‐scale fluctuations water vapor temperature that are unresolved large‐scale ...

The fine particles serving as cloud condensation nuclei in pristine Amazonian rainforest air consist mostly of secondary organic aerosol. Their origin is enigmatic, however, because new particle formation in the atmosphere is not observed. Here, we show that the growth of organic aerosol particles can be initiated by potassium-salt-rich particles emitted by biota in the rainforest. These partic...

During the Ice in Clouds Experiment–Layer Clouds (ICE-L), aged biomass-burning particles were identified within two orographic wave cloud regions over Wyoming using single-particle mass spectrometry and electron microscopy. Using a suite of instrumentation, particle chemistry was characterized in tandem with cloud microphysics. The aged biomass-burning particles comprised ;30%–40% by number of ...
