“…Such transformations in aerosol particles affect both the environment and human health Tang et al, 2006;Wei et al, 2009). In the context of their close relationship to aerosol surface area, morphology, surface chemical composition, structure and other surface characteristics (Zhu et al, 2010;Lazzeri et al, 2003;Xu, 2006;Li et al, 2007;Li et al, 2010;Wu et al, 2009;Lu et al, 2013;Bluhm and Siegmann, 2009;Sobanska et al, 2014), study of the surface physicochemical characteristics of aerosol particles has become an important aspect of aerosol particle research.…”

“…For instance, iron (Fe) rich minerals and clays absorb short wave (visible and ultraviolet) radiation, whereas quartz and calcium (Ca) rich minerals absorb more long wave (infrared) radiation (Sokolik and Toon, 1999;Hudson et al, 2008a;Hudson et al, 2008b;Kleiber et al, 2009;Klueser et al, 2012;Laskina et al, 2012). Individual particles in the atmosphere are often mixtures of multiple minerals (Ault et al, 2012;Sobanska et al, 2012;Jung et al, 2014;Sobanska et al, 2014), which complicates understanding their specific optical properties. Determining the relative amounts of these minerals in the dust will allow for a more accurate calculation of their optical properties and ultimate effect on snow melt.…”

Transported mineral dust deposition to remote mountain snow decreases snow albedo and increases absorption of solar radiation, which accelerates snowpack melt and alters water supply. Mineralogy and chemical composition determine dust particle optical properties, which vary by source region. While impacts of dust deposition at remote mountain sites have been established, few studies have connected the chemical composition of ambient particles during deposition events with the properties of those deposited on the snowpack. Ambient particles and surface snow were sampled in the San Juan Mountains of southwestern Colorado, which frequently experiences dust deposition in the spring and has evidence of dustenhanced snow melt. Individual particles were analyzed using scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX). The number concentration and size distribution of insoluble residues in the top level of snow were determined with nanoparticle tracking analysis (NTA). During a minor dust event (April 2-3, 2015), the fraction of absorbing iron-enriched dust in the ambient aerosol, the number concentration, and size of insoluble residues in snow all increased. This can be traced to shifts in mineral dust source region within the Colorado Plateau, during which, there were higher wind speeds leading to increased transport. The shift in chemical composition and mineralogy of the transported dust has the potential to impact snowpack radiative forcing during dry deposition. In addition, it can also modify the snowpack through scavenging of particles during wet deposition, as well as alter the properties of clouds and orographic precipitation. Understanding these impacts is crucial to understanding the hydrological cycle at remote mountain sites.

“…Several analytical techniques have been used for single particle analysis, including electron microscopy (Li et al, 2016), aerosol-time-of-flight mass spectrometry/single particle aerosol 25 mass spectrometry (Zhang et al, 2015), atomic force microscopy (AFM) (Posfai et al, 1998), and scanning transmission Xray microscopy with near-edge X-ray absorption fine-structure spectroscopy (Pöhlker et al, 2012). Raman spectroscopy offers obvious advantages in non-destructive, ultrasensitive, and rapid detection, making it a promising technology for single particles analyses (Batonneau et al, 2006;Nelson et al, 2001;Sobanska et al, 2012;Ault et al, 2013;Sobanska et al, 2014; Atmos.

“…However, continued improvements of the feasibility and practicality of SERS spectroscopy are needed to probe the most important individual particles affecting the climate and human health (Ault and Axson, 2016) (Ofner et al, 2015). Our previous work focused on NP design and fabrication (Sun et al, 2016b) for SERS detection of environmental pollution in solution, such as mercury ions (Sun et al, 2016a), hexavalent chromium (Lv et al, 2017), polycyclic aromatic hydrocarbons (Du et al, 2016), and polybrominated diphenyl ethers . 15…”

Abstract. Fine particle associated with haze pollution threatens the health of more than 400 million people in China. It is therefore of great importance to thoroughly investigate and understand its composition. To determine the physicochemical 10 properties in atmospheric fine particles at the micrometer level, we described a sensitive and feasible surface-enhanced Raman scattering (SERS) method using Ag foil as a substrate. This novel method enhanced the Raman signal intensities up to 10,000 a.u. for ν(NO 3 -) in fine particles with an enhancement factor of at least 56. The SERS effect of Ag foil was further studied experimentally and theoretically and found to have an enhancement factor of the order of ~ 10 4 . Size-fractionated real particle samples with aerodynamic diameters of 0.4-2.5 µm were successfully collected on a heavy 15 haze day, allowing ready observation of morphology and identification of chemical components, such as soot, nitrates, and sulfates. These results suggest that the Ag foil based SERS technique can be effectively used to determine the microscopic characteristics of individual fine particles, which will help to understand haze formation mechanisms and formulate governance policies.
