TL;DR: In this paper, the authors used a global aerosol microphysics model to simulate the impact of residential fuel combustion on atmospheric aerosol for the year 2000 and used a concentration response function to estimate the human health impact due to long-term exposure to ambient PM2.5 from residential emissions.

TL;DR: In this paper, the authors measured non-refractive submicron aerosols (NR-PM1) and black carbon over a one year period in Welgegund, and investigated the seasonal and diurnal patterns of aerosol concentration levels, chemical composition, acidity and oxidation level.

Correction for a measurement artifact of the Multi-Angle Absorption Photometer (MAAP) at high black carbon mass concentration levels

TL;DR: In this article, the authors show correction methods for an artifact found to affect the instrument accuracy in environments characterized by high black carbon concentrations, which is caused by erroneous dark counts in the photodetector measuring the transmitted light, in combination with an instrument internal averaging procedure of the raw signals.
