Student Research Opportunities:

Our Atmospheric Imaging group utilizes state-of-the-art monochromatic imaging systems and novel infrared cameras to study a broad range of atmospheric optical phenomena. These include atmospheric gravity waves, mesospheric airglow emissions and temperatures, noctilucent clouds, equatorial F region dynamics, high-latitude aurora, meteor storms, satellite reentry and lightning-induced optical transients termed "sprites" and "elves". Our field measurements extend from the equator to the polar regions, participating in ground-based campaigns and satellite coordination studies, most recently with the NASA AIM mission to investigate Polar Mesospheric clouds. Currently we operate CCD imagers at Bear Lake Observatory, Utah,and Star Valley High School, Wyoming for tomographic measurements, and Rothera Station, Antarctica. New coordinated measurement programs at Sierra Pachon, Chile, ALOMAR Observatory, Norway, and South Pole station, Antarctica will start in 2009. Graduate and undergraduate students are involved in all aspects of our research including field measurements, image and satellite data analysis, conference presentations and publications.
