Dr. Curtisí research interests include the spectroscopic properties of atmospheric aerosol particles. Particles in the atmosphere affect visibility, global climate, and human health, yet their optical properties and effects on Earthís radiation budget are poorly understood.
The Curtis lab currently performs laboratory and field measurements of the absorbance and scattering of light by naturally occurring aerosol particles and their interaction with pollution gases to determine their effect on global climate and visibility. In addition, the optical properties of the particles are needed to interpret remote sensing data of particles from space and ground-based measurements.
Spectroscopic techniques used in the Curtis lab include cavity ringdown spectroscopy (CRDS), UV/Vis diffuse reflectance spectroscopy, UV/Vis transmission spectroscopy, and laser spectroscopy of angular scattering from particles.
