Research Interests

To this day, a lack of understanding exists on the role atmospheric aerosol has on climate change. Aerosol can directly affect climate by absorbing, scattering, and re-emitting incoming solar and outgoing terrestrial radiation. Aerosol can also indirectly affect climate by acting as cloud condensation nuclei. Further, the composition of atmospheric aerosol can change as they react with man-made pollutants. Our laboratory uses a number of instruments to measure the radiative properties of aerosol (Fourier transform infrared spectroscopy) as well as the cloud forming potential of aerosol (quartz crystal microbalance and tandem differential mobility analyzer). By better understanding the properties of aerosol we can provide information to atmospheric modelers to better predict climate change.

Hudson Group Activities

March 2011

Undergraduate Steve Schill presented a talk, "Comparison of complementary techniques for water uptake studies of atmospheric aerosol" at the Western Regional Honors Council Conference in Park City, UT. He also presented a brief version of this talk at the 241st ACS National Meeting in the New Analytical Methods and Approaches section of the Analytical Chemistry Division.

Undergraduate Tiffany Lopez presented a poster entitled "FTIR measurements of atmospherically relevant mixtures: Implications for climate modeling" in the Undergraduate Poster Session of the Chemical Education Division
