I perform ecosystem modeling within the ARM Southern Great Plains Carbon Program. I apply, develop, and test models to:

• simulate ecosystem carbon, water, and energy fluxes for a variety of land uses

• simulate ecosystem isotope (¹⁸O and ¹³C) fluxes and stocks, and apply these models to improve our representations of ecosystem fluxes

• study global patterns of atmospheric C18OO and the relationship of these patterns to ecosystem processes

• simulate and better understand coupled soil nitrogen and carbon cycles and nitrogen trace-gas emissions

• estimate distributed ecosystem fluxes, and compare these fluxes to measured values
• simulate coupled ecosystem and mesoscale meteorological processes

This modeling effort is intended to improve our ability to estimate regional-scale ecosystem fluxes, and their potential impact on local, regional, and global climate.

My primary research area continues to be about understanding the Carbon cycle focusing on atmospheric measurements (continuous and flasks samples) at a condimental site located in the Southern Great Plains of the US. This site is part of the ARM (Atmospheric Radiation Measurements) Climate Research Facility (ACRF) domain. The carbon measurement and analysis activities that I contribute to include:

1. carbon eddy flux systems
2. continuous high-accuracy CO2 measurements and CO2 isotope collection
3. aircraft and tower flask contributions to the NOAA Climate Monitoring Diagnostic Laboratory
4. global network
5. continuous high-accuracy CO measurements
6. continuous high-accuracy aircraft measurements.
