Synergistic Activities
I develop and deploy photoacoustic instruments for measurement of black carbon emission from vehicles in source sampling, and in ambient air quality studies. These measurements are often combined with other real time particulate emission measurements for the larger purpose of establishing detailed knowledge of the conditions giving rise to most of the black carbon and particulate emission to the atmosphere, and their environmental impacts. I also teach courses in the Atmospheric Sciences Program and Physics Department at the University of Nevada, Reno. For example, my course in Atmospheric Radiation Transfer takes a hands-on approach. Students learn the theory of FTIR instruments, then use one to make measurements of the downwelling IR spectral radiance from 500 to 2000 1/cm. With this motivation, students develop a theoretical understanding, and numerical model, that seeks to explain their measurements. A simple 1-D model is developed and explored to understand multiple scattering.
