TL;DR: Alphasense OPC-N2 as mentioned in this paper is a low-cost miniature optical particle counter for monitoring ambient airborne particles at typical urban background sites in the UK, which is evaluated by co-locating 14 sensors at a site to investigate the variation in measured concentrations.

TL;DR: This review explores the understanding of aerosol particle phase, particularly as identified by measurements of the viscosity of organic particles, and the atmospheric implications of phase state.

TL;DR: Compounds with equilibrium vapor pressures in this range will exhibit the greatest sensitivities in terms of their gas to particle partitioning to uncertainties in their saturation vapor pressures, with consequent impacts on the ability of explicit and semiexplicit chemical models to simulate secondary organic aerosol formation.

TL;DR: In this paper, the hygroscopicity of pollen is measured under subsaturated relative humidities using an electrodynamic balance, and it is found that while pollen grains are only moderately hydrastic, they can activate at critical supersaturations of 0.001% and lower, and thus pollen grains will readily act as cloud condensation nuclei.

TL;DR: The European project RECONCILE has comprehensively addressed remaining questions in the context of polar ozone depletion, with the objective to quantify the rates of some of the most relevant, yet still uncertain physical and chemical processes as mentioned in this paper.
