Key points AERONET operates more than 500 ground-based remote sensing sites around the globe measuring atmospheric ...

When clouds form around aerosols, such particles can absorb solar energy from the atmosphere and thereby reduce sunlight at ground level. And if clouds are not present, aerosols can reflect sunlight ...

Aerosols are fine particulates that float in the atmosphere. Many are natural, but those haven’t increased or decreased much over the centuries.

Clouds play an important role in regulating the climate. Bright ones at low altitudes generally reflect solar energy away, ...

Atmospheric scientists have long suspected that microscopic aerosol particles from industrial processes increase the brightness of clouds, resulting in greater reflection of sunlight and cooling ...

Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions. Rising 2,225 meters into the air on ...

Aerosol particles are crucially important to the chemistry of the atmosphere, influencing both climate and air quality. This Review discusses progress in understanding the radical-initiated ...

Wildfires have spread across the planet for millennia, but they are increasing as the climate warms. Decimated forests, ...

The spatial distribution of ambient aerosol particles plays a huge role in aerosol–radiation–cloud interactions; however, not enough sampling has been done from the atmospheric boundary layer ...

According to NASA, the PACE satellite can map atmospheric aerosols and differentiate how they absorb light and heat, characterizing them as "light" or "dark" in nature. Climate scientists say this ...

Atmospheric aerosols are particles that are 100–10,000 times smaller than the diameter of a hair, and their concentration in the atmosphere is in the range of hundreds to hundreds of thousands per ...
