Like other tiny atmospheric particles called aerosols, black carbon (BC) has a short lifetime in the atmosphere of about a week because it is removed by rain or snow.
The planet's albedo, around 30 percent, is governed by cloud cover and the quantity of atmospheric particles called aerosols.
That's the conclusion of a team of scientists using a new approach to study tiny atmospheric particles called aerosols that can influence climate by absorbing or reflecting sunlight and seeding clouds.
Not exact matches
The team started by looking at the formation of the very small particles — a process called aerosol nucleation — by mimicking atmospheric conditions inside an ultraclean steel «cloud chamber», which Kirkby says is the cleanest ever created.
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.
It can attach to dust particles and rain out of the sky, in a process called atmospheric deposition.
Some atmospheric VOCs combine with oxygen to form tiny airborne particles called oxygenated VOCs (oVOCs), which insulate the atmosphere and lead to warming.
Yet these particles, called secondary organic aerosols, are a dominant atmospheric component in most megacity locations.
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.
Results: Tiny bits of atmospheric dust and particles called aerosols may play a big role in global climate change, but just how big a role is not well understood.
