Project Descriptions:

Intern Pam Spier worked with Nicole Molders on a project involving how well the Hydrothermodynamic Soil Vegetation Scheme (HTSVS) performed in arctic regions. HTSVS has already been shown to perform well at mid-latitudes. My project showed that it performed well in arctic regions and will soon be used in climate models worldwide.

Jessica Proud worked on developing a probe used to measure snow grain size. Along with advisor William Simpson and other UAF grad students, Jess helped to build and test a near-infrared probe that will be able to determine the size of snow grains during field experiments in the future.

Also working with Nicole Molders was Anne Cherry. Anne's project was an evaluation of MM5 Simulations With HTSVS with and without inclusion of soil-frost parameterizations. Anne's project concluded that soil-frost parameters improve low altitude and extended time forecasts, mean error under prediction, moderate precipitation forecasts, and overall forecast accuracy.

Sarah Kvasnicka, with a grad student from the University of Texas and advisor Dr. William Simpson, studied PAN photolysis using Cavity Ring-down Spectroscopy.

Paul Gradney worked with Dr John Olson on the CTBT infrasound project for the Fairbanks, AK and Windless Bight, Antartica arrays. During his time over the summer he catalogued signals and developed programs for tracing the propagation of sound as it traveled through the atmosphere.
