Four NOAA scholars and one Howard Hughes Medical Institute Fellow interned at the Atmospheric Turbulence and Diffusion Division of ARL during the summer of 2009. David J. Gagne II, a NOAA Hollings scholar from the University of Oklahoma, was mentored by Ron Dobosy and utilized RAMAN network data to evaluate model output statistics (MOS) in the East Tennessee WRF Model Domain. Another Hollings scholar, Kenneth Pratt from Pennsylvania State University worked with Will Pendergrass to study the effects of stability on fine particulate matter concentrations in a unique topographic area surrounding the I-40/Watt Road interchange in Knoxville, TN. NOAA EPP scholar Aziza Marchant from Savannah State University teamed with Tilden Meyers to evaluate the relationship between aspirated and non-aspirated temperature sensors in support of U.S. CRN power management. Samuel Ubanyionwu, a NOAA EPP scholar from Texas Southern University, was mentored by LaToya Myles and measured concentrations of atmospheric compounds (including nitric acid and PM2.5 sulfate) along the Mississippi Gulf Coast during a collaborative field program with Jackson State University. Spelman College Howard Hughes Summer Research Visiting Fellow Ridwaana Allen was mentored by LaToya Myles and measured ambient ammonia concentrations at two sites in East Tennessee to determine influences of possible emission sources.

In addition to completing their assigned projects, the summer interns each presented their research during a joint ARL seminar in early July 2009. The NOAA scholars also presented their work at the 2009 Science and Education Symposium at NOAA Headquarters in Silver Spring, MD. Several interns have continued to work with their respective mentors to develop their projects into extended abstracts and manuscripts for publication.
