How do sulfate aerosols affect the temperature of the planet? • By absorbing <strong>and</strong> emitting infrared, sulfate aerosol keeps the nighttime warmer than it would be without them • By reflecting sunlight during the day, sulfate aerosol keep the daytime cooler than it would be without them
Diurnal Range • The diurnal range has decreased by more than 1 K in the last century • In major fossil fuel burning regions, radiative observations show that anthropogenic aerosol reflects 2 – 10 W m^2 of solar energy back to space across N. America <strong>and</strong> Eurasia
