Why It Matters: Aerosols,
tiny airborne particles of dust and pollution suspended in the atmosphere, affect the atmosphere and the surface of Earth by scattering and absorbing light.

Believe it or not, sneezing is a reflex mechanism that allows newborns to clear their
tiny nasal passages and airways
of airborne particles and congestion.
Their stickiness makes it hard to get them through an inlet into a measuring device, but these compounds may play a significant role in the formation and alteration
of aerosols,
tiny airborne particles that can contribute to smog or to the nucleation
of raindrops or ice crystals, affecting the Earth's climate.
To investigate the layers and composition
of clouds and
tiny airborne particles like dust, smoke and other atmospheric aerosols,, scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland have developed an instrument called the Cloud - Aerosol Transport System, or CATS.
A team
of scientists led by Pacific Northwest National Laboratory atmospheric researcher Dr. Susannah Burrows and collaborator Daniel McCoy, who studies clouds and climate at the University
of Washington, reveal how
tiny natural
particles given off by marine organisms —
airborne droplets and solid
particles called aerosols — nearly double cloud droplet numbers in the summer, which boosts the amount
of sunlight reflected back to space.
But it can also stir up
tiny particles that can become
airborne and inhaled; some models even spew dust and allergens out
of their exhaust vents.
Over the last century,
tiny airborne particles called aerosols, which cool the climate by absorbing and reflecting sunlight, have largely cancelled out the effects
of GHG emissions on tropical storm intensity, according to a new scientific review paper published in Science journal.
NASA's P - 3 research plane begins flights this month through both clouds and smoke over the South Atlantic Ocean to understand how
tiny airborne particles called aerosols change the properties
of clouds and how they influence the amount
of incoming sunlight the clouds reflect or absorb.
