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.
