We should study
aerosols, tiny pieces of solid and liquid in the air, because of how much
humans affect it and it affects climate. By studying aerosols we provide ground
based data that adds to satelitte sensing. There are some natural ways that
aerosols are put into the atmosphere such as dust in the wind, forest fires,
and volcano eruptions. We can track the effect of these natural causes.
Humans put a lot of
aerosols in the atmosphere as well. We do this through the daily use cars,
power plants, factories, etc..
Clouds get help forming
from aerosols. But in the absence of clouds lightabsorption that is not caused
by atmospheric gas is from aerosols. Also, sunlight is absorbed and sometimes
scattered (this is called atmospheric optics).If you know the angle of the sun
and atmospheric pressure, you know the amount of gas between the earth and the
sun. Other affects are that aerosols can affect breathing and limit visibility.
