Aerosols are tiny particles suspended in the air. Most occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation, and sea spray (Figure 1). Human activities, such as the burning of fossil fuels and the alteration of natural surface cover, also genera...
Aerosols impact human and environmental health as well as global climate. In this presentation I will aim to summarize the state of the science of atmospheric chemistry research related to particulate matter (PM) and the challenges ahead. The key questions in aerosol research are linked to ...
Science Shooting Reflective Aerosols Into the Stratosphere Won't Stop Global Warming But it sure sounds cool. By Caroline DelbertPublished: Jun 09, 2020 12:43 PM EDT Save Article AleksandarGeorgiev//Getty Images Researchers from MIT have found that reflective aerosol clouds could deaden some global...

climate science was very much in its infancy — scientists were just learning to decipher the influence of competing forces regulating climate. In the 1960s and 1970s, the science began to mature as researchers unearthed the most prominent factors such as the cooling influence of aerosols and the...
around the internet, including droplet, aerosol and microdroplet. Microdroplets and aerosols are synonymous: These terms both refer to fine particles that can exist in the air for long periods of time and travel long distances. Droplets, on the other hand, are larger and do not travel as far...
As the satellite passes over the dune field (gray region), the CALIPSO (green line) scan of the atmosphere detects high backscatter β from aerosols in the mixed layer relative to the free atmosphere above (blue map, 5-km horizontal resolution). The mean difference (red line) of the ...
There are other natural climate drivers, also known as “climate forcings”. Large volcanic eruptions qualify as climate forcings because sulfur dioxide emissions from eruptions can have a temporary cooling effect. Sulfur dioxide converts into sulfuric acid that condenses into aerosols in the atmosphe...
