A Brazilian study published in the journal Communications Earth & Environment shows how wildfires and forest burning for agriculture influence rain cloud formation in the Amazon. According to the authors, aerosols (tiny solid particles and liquid droplets emitted into the atmosphere by fire) hinder the freezing of cloud droplets when the atmosphere is humidified, but can also promote freezing when the atmosphere is dry

This alters the natural functioning of clouds and their typical height, and may also affect precipitation and the amount of sunlight reaching the ground. To arrive at this conclusion, the scientists used a large dataset collected over a 15-year period, from 2000 to 2014, involving satellite imagery from the United States National Oceanic and Atmospheric Administration (NOAA), measurements of atmospheric aerosols from fires made by NASA's Aerosol Robotic Network (AERONET), and reanalysis data from the European Center for Medium-Range Weather Forecasts (ECMWF).
