Graduate Student Participates in Coop at Argonne

This summer, NIU Department of Geography graduate student Jenni Prell worked among scientists in the Environmental Science Division at Argonne National Laboratory, a Department of Energy research center, under a Graduate Cooperative Education Appointment. Her main project was to assist in adjusting a climate model for biofuel research through the guidance of her supervisor Dr. V. Rao Kotamarthi. The goal of the ongoing project is to show what changes might occur in our environment if current land use practices were switched to grow crops used for different forms of biofuels. The Community Land Model (CLM) is being used to model these changes, but the version did not originally include crops as a plant-functional type (pft). Corn, wheat, and soybean were added into the model as crops that would be likely used for biofuel production, and Jenni's task was to develop a carbon allocation scheme that would distribute carbon, beginning from seed to harvest, to different parts of each plant. She was able to build on her computer programming skills to implement these changes into the model, while expanding her knowledge of crop dynamics. Jenni drew upon other models and scientific literature to help solidify the allocation scheme.

Aside from working on biofuels research, Jenni was also able to take part in various other responsibilities at Argonne. She assisted in measuring, collecting, and downloading Multispectral Radiometer (MSR) and Leaf Area Index (LAI) data at outdoor sites at Fermilab, which allowed her to get up close and personal with field instruments. Jenni also assisted meteorologist and instrument mentor Michael Ritsche in preparing new instruments for deployment to the Barrow, Alaska field site of the Atmospheric Radiation Measurement (ARM) program. The replacement of these instruments will be the focus of Jenni's thesis work, researching data quality issues of meteorological instrument change-outs.

Jenni earned her B.S. in Meteorology from NIU in Dec. 2007 and is currently working towards her M.S. in Geography/Meteorology at NIU.
