Data from: Thirdhand smoke uptake to aerosol particles in the indoor environment
Aerosol composition measurements made in an indoor classroom indicate the uptake of thirdhand smoke (THS) species to indoor particles, a novel exposure route for THS to humans indoors. Chemical speciation of the organic aerosol fraction using mass spectrometric data and factor analysis identified a reduced nitrogen component, predominantly found in the indoor environment, contributing 29% of the indoor submicron aerosol mass. We identify this factor as THS compounds partitioning from interior surfaces to gas phase and then aerosol phase. Partitioning of THS vapors to aerosols requires an aqueous phase for reactive uptake of the reduced nitrogen species (RdNS), leading to seasonal differences in THS concentration indoors. RdNS protonate under the acidic conditions expected for indoor aerosols of outdoor origin. Controlled laboratory measurements performed using cigarette smoke deposited into a Pyrex vessel showed a similar partitioning behavior to aerosol of outdoor origin and mass spectral features comparable to the measured indoor THS factor after 1 week of residence time in the closed vessel. This study reports a new, potentially large THS exposure route from partitioning of surface volatile organic compounds into the aerosol phase and subsequent dispersion in a mechanically ventilated building.

Input data for article "Large eddy simulation of the optimal street-tree layout for pedestrian-level aerosol particle concentrations"
<p>Input dataset used when performing LES simulations for journal article "Large eddy simulation of the optimal street-tree layout for pedestrian-level aerosol particle concentrations" (Karttunen et al., in preparation). The dataset was used with the PALM model system revision 3698 and most likely it won't work on older or newer versions.</p> <p>Instructions for use:<br> A precursor run must be run first. Output data (BINOUT) of it should be linked into a BININ directory of the actual scenario runs. You'll most likely have to tweak the CPU grid settings in ENVPAR and PARIN files in order to fit them to your computational resources. For more information on usage please refer to the PALM model documentation available online in <a href="https://palm.muk.uni-hannover.de/trac/wiki/doc">https://palm.muk.uni-hannover.de/trac/wiki/doc</a>.</p>

Quantifying particle-to-particle heterogeneity in aerosol hygroscopicity
<p>Chemical compositions in an aerosol polulation can generally be classified into the nearly hydrophobic (NH), the less hygroscopic (LH), and the more hygroscopic (MH) components according to their capacities of water absorption. The distribution of these three components varies between and within particles due to the complex sources and aging processes, causing the particle-to-particle heterogeneity in aerosol hygroscopicity. Although this heterogeneity is of great importance to the evaluation of aerosol climatic and environmental effects, it has not been paid attention to in previous studies. This study proposes an algorithm to quantify the particle-to-particle heterogeneity from in-situ measurements for the first time. This algorithm can efficiently characterize the evolution of aerosol heterogeneity with time in the atmosphere and provide a framework for quantifying heterogeneities to merge observations into numerical models to deeply investigate how heterogeneity in aerosol hygroscopicity influences aerosol effects on climate and environment.</p>
