TL;DR: In this paper, three methods are implemented to obtain a best estimate of dominant aerosol type at each station using aerosol optical properties, which can help expand the current knowledge of spatiotemporal variability in aerosol types globally, particularly where chemical composition measurements do not exist concurrently with optical property measurements.

TL;DR: In this article, the authors provide the widest effort so far to document variability of climate-relevant in situ aerosol properties (namely wavelength dependent particle light scattering and absorption coefficients, particle number concentration and particle number size distribution) from all sites connected to the Global Atmospheric Watch network.

TL;DR: In this article, a long-term trend analysis of aerosol optical properties was performed on time series from 52 stations situated across five continents, and the results showed that scattering and backscattering coefficient trends are mostly decreasing in Europe and North America and are not statistically significant in Asia, while polar stations exhibit a mix of increasing and decreasing trends.

TL;DR: To estimate global aerosol radiative forcing, measurements of aerosol optical properties are made by the National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laborat... as discussed by the authors.

TL;DR: In this paper, a sensitivity study was performed to assess the impact of data availability on Ntot's annual and seasonal statistics, as well as on the analysis of its diel cycle.
