Smithlab
We study the optical properties and chemistry of atmospheric aerosols.
We study the optical properties and chemistry of atmospheric aerosols.
The Smithlab studies how aerosol particles in the atmosphere interact with sunlight. We design novel instruments, carry out laboratory experiments, sample ambient air and develop machine learning models for predicting aerosol optical properties. What we learn about how particles scatter and absorb light helps improve how models predict future climate, how satellites make measurements through the atmosphere and how air quality is impacted.

The Smithlab and Prof. Al Fischer (Smithlab alum) are making measurements of aerosol optical properties from simulated wildland fires at G-WISE 2 at the U.S. Forest Service Athens Prescribed Fire Science Laboratory and led by Prof. Rawad Saleh (UGA Engineering).

Congratulations to Zach McQueen who was recently awarded a NASA Post-doctoral Researcher Fellowship. Zach will be working at the NASA Goddard Space Flight Center where will be conducting research on Titan's atmosphere.
October 2024
Ryan, John and Geoff attended the annual meeting of the American Association for Aerosol Research (AAAR) where they each gave platform presentations: Ryan on interpreting the aethalometer DualSpot correction, John on coated black carbon particle analysis, and Geoff on clustering based on aerosol optical properties.
