The MSUM Physics & Astronomy Seminar Series Presents:
Examining the Radiative Properties of Atmospheric Aerosols: From Laboratory Measurements to Global Radiative Transfer Models
by: Dr. Brian Meland (MSUM alumnus)

The focus of this research is the radiative properties of atmospheric mineral dust and its resulting impact on radiative forcing in the Earth’s atmosphere. This talk will include a brief overview of light scattering theory as it applies to particulate matter in the 10 nm to 2 um size range as well as how the shape of atmospheric aerosol play a role in affecting radiative properties. Results will be shown for light scattering measurements of typical atmospheric aerosols taken under laboratory conditions and via field measurements. Finally, results of large scale atmospheric models of aerosol effects will be presented.
