That's a good site lucidvisions, but I couldn't find any mention of scientists producing aerosols, only passive research.
Huge amounts of international research take place every year into aerosol investigations, but in almost every case the aerosols under study are
produced by industrial or other normal man made processes such as factory chimneys or car pollution, forest fires etc.
A typical example is the recently held NorthEast Aerosol eXperiment (NEAX).
This summer, scientists from the DOE's Argonne National Laboratory, Brookhaven National Laboratory, and Pacific Northwest National Laboratory will be
participating in the International Consortium for Atmospheric Research on Transport and Transformation (ICART2) experiment, an effort to understand
how pollutants from the Northeastern U.S. affect climate and air quality as they spread over the North Atlantic Ocean. Other collaborators include the
National Atmospheric and Oceanographic Administration (NOAA), the National Aeronautics and Space Administration (NASA), the University of New
Hampshire, and others.
The DOE scientists, funded and coordinated by the Office of Biological and Environmental Research (OBER) within DOE's Office of Science, will focus
on sampling aerosol pollutants and evaluating their effects on Earth's radiation balance and climate forcing for a portion of the study known as the
NorthEast Aerosol eXperiment (NEAX). They will conduct regional air-sampling flights from Latrobe Airport, located about 25 miles east of Pittsburgh,
Pennsylvania, from July 15–August 15 aboard a G-1 Gulfstream research aircraft operated by PNNL carrying research-grade instruments developed at both
BNL and PNNL. Additional ground-based instruments deployed by ANL and PNNL scientists will provide complementary data.
Aerosols such as sulfur compounds result from emissions by fossil-fuel-burning power plants and other industrial processes. By themselves, and by
affecting the brightness of clouds, they may increase the amount of incoming sunlight that is reflected back into space, thereby exerting a partial
cooling effect on Earth's climate. But because their concentrations are highly variable and because they are removed from the atmosphere fairly
quickly, it is difficult to assess these effects and the impact of aerosols on climate without collecting real data.
So the scientists participating in NEAX will conduct studies of aerosol formation and growth in point source and urban plumes with different
characteristics. They'll also conduct air-mass scale studies to see how the chemical, microphysical, and optical properties of aerosols evolve as the
air-mass ages and is transported away from its source. Ultimately, they hope to characterize how much aerosols and aerosol precursors in the Midwest
contribute to the aerosol burden in the western North Atlantic.
