Students continued research on the hydrologic cycle begun in the CAU REU program in 2001. Under guidance of the PI and ESSP scientists, a team of 8 students spent up to 5 weeks on 24-hour shifts, 7 days per week, measuring the environmental parameters needed to understand the relationship of tree response to evapotranspirative pumping by the atmosphere. These parameters include soil moisture and temperature profiles, identification of soil and tree types, cloud cover, atmospheric pressure, temperature, humidity, insolation, net radiation beneath the tree canopy, sensible and latent heat, momentum flux, soil heat flux, tree circumference changes, surface emissivity and radiative temperature, canopy radiative temperature, barometric pressure, latitude and longitude, and related soil measurements. More advanced students attempted to analyze energy and momentum flux components from direct measurements with the ESSP’s sonic anemometer and krypton hygrometer. The goal of this research is to find a relationship between tree circumference changes and the movement of water from the ground through the trees to the atmosphere. It is hoped that a GLOBE protocol might eventually be developed based on this research. Students constructed some of their own sensors for this project.
Students also worked on the USRA/NASA (Universities Space Research Association/National Aeronautics and Space Administration)-sponsored project to develop an instructional module in energy balance for use at the undergraduate, graduate and professional levels. The undergraduate module is qualitative in nature, having the students estimate energy balance
components in the form of arrows pointing toward or away from a line, which represents the air/land interface. The graduate and professional options require actual energy fluxes to be estimated from AEMN (Georgia Automated Environmental Monitoring Network) station data throughout Georgia. Latitude and longitude inputs allow the module to be used in an international setting.
