Margaret Tolbert's Research Interests
My interests are in the area of heterogeneous atmospheric chemistry, focusing on the chemical, physical, and optical properties of atmospheric aerosols. In addition to fundamental studies of particles, we are also exploring how atmospheric aerosols impact current problems such as stratospheric ozone depletion, global climate change, urban smog, and visibility degradation.
Research in the Tolbert group is not limited to studies of atmospheric aerosols on the current-day Earth. We are also probing the particles that might have been present at the earliest times in Earth’s history. We are interested in how these particles might have impacted the climate of early Earth and the development of life on Earth. As a parallel to early Earth, we are also studying aerosols and clouds on other planetary bodies such as Mars and Saturn’s moon Titan.
Our work is primarily laboratory based, but involves collaborations with theory teams and those involved in fieldwork. Our primary support comes from the National Science Foundation and NASA.
