TL;DR: In this paper, the authors compare with ground-based AERONET observations of aerosol optical depth (AOD) to within expected accuracy more than 60% of the time over ocean and more than 72% over land.

TL;DR: Satellite data over the Amazon region during the biomass burning season showed that scattered cumulus cloud cover was reduced from 38% in clean conditions to 0% for heavy smoke, which reverses the regional smoke instantaneous forcing of climate.

TL;DR: The literature on atmospheric particulate maffer (PM), or atmospheric aerosol, has increased enormously over the last 2 decades and amounts now to some 1500-2000 papers per year in the refereed literature.

TL;DR: There is low probability that the net aerosol effect can be explained by coincidental, unresolved, changes in meteorological conditions that also accumulate aerosol, or errors in the data, although further in situ measurements and model developments are needed to fully understand the processes.

TL;DR: In this article, the authors used MODIS data to distinguish dust from smoke and maritime aerosols and to evaluate the African dust column concentration, transport, and deposition, and found that 240 ± 80 Tg of dust are transported annually from Africa to the Atlantic Ocean, 140 ± 40 Tg are deposited in the Atlantic ocean, 50 Tg fertilize the Amazon Basin (four times as previous estimates, thus explaining a paradox regarding the source of nutrition to the Amazon forest), and 20 Tg return to Africa and Europe.
