TL;DR: In this article, the authors compared commercial and custom-made inversion routines to calculate the particle number size distributions from the measured electrical mobility distribution, and concluded that the consistency of these reference instruments to the total particle number concentration was less than 5%.

TL;DR: In this article, the authors investigated the relationship between aerosols number size distribution and air quality in terms of particulate matter (PM) mass concentrations (as usually monitored in the air quality networks) on the other hand.

TL;DR: The results from a calibration and intercomparison workshop where several units of the three most widely used nephelometer models were tested with respect to their CO2 calibration accuracy and stability and non-idealities of their angular illumination function are reported in this article.

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 paper, the authors compared observations from the European Commission Atmospheric Observatory of Ispra (regional background) and from the regional environmental protection agency (ARPA) air monitoring stations in the Milan conurbation (urban background) using two different approaches.
