Title: Aerosol particles in the Earth’s atmosphere

Location: 1520-516

Time: 3pm

Abstract:

Aerosol particles are omnipresent in the Earth’s Atmosphere.  Their size, concentration, phase, morphology and chemical composition determines their impact on air quality, climate and human health.   Particles can be emitted directly into the atmosphere from processes such as combustion, oceanic wave-breaking and volcanic activity. They can also be formed in the atmosphere by nucleation of low-volatility vapors followed by condensational growth.  This talk will address and discuss the sources, properties and climate impact of atmospheric particles and present state of the art methods for studying them.
