• Initial research
• Hydrology modeling at H.J. Andrews LTER (Oregon)
• Georgia Tech Hydrology Model (TOPMODEL)
• Interest in applying to additional ecosystems
• Chesapeake Bay

• Kansas City air pollution concerns• Clean air = government money• Pollution = less/no money
• Issue concerning spike in particulate matter… city questionsburning in the Flint Hills
• How does burning in the Flint Hills impact air quality in KC?

• ORD – Region 7 team up
• How to address this question…? • Models
• Things to consider• What is burning… ? (land cover)• How much… ? (total biomass)• What is in it… ? (nutrients)• Contributing… ? (hydrology, climate)

• Development of a Multi-Model Ecosystem Simulator• Modify models to run i/o from each other
• Single set of input variables
• Modifiable • Application to different ecosystems
• Distribute for use
• Future (phases 2 and 3)• Links to air quality models• Alternative futures
• Scenario based changes over time

• Tasks• Regional ecosystem modeling in the Flint Hills• Local ecosystem modeling in Konza Prairie
• Focus on the Kings Creek watershed• Use for calibration of regional models
• Slight differences between models• Mainly due to scale issues
• Hydrology• Regional vs. local climate

• Eastern Kansas into Northern Oklahoma
• Originally Bluestem Pastures, renamed for high chert content
• Primarily used for grazing, as land not suitable for tillage
