Chaoqun Lu's lab research integrates ground/satellite observations into process-based ecosystem modeling framework to examine how human activities (e.g., anthropogenic climate change, air pollution, land use and management, etc.) and natural disturbance combined to affect the environmental sustainability. Research topics include coupled biogeochemical and hydrological cycles, land-atmosphere exchange of greenhouse gases (CO2, CH4 and N2O), and water discharge and nutrient movement from land to aquatic systems at multiple scales ranging from watershed, regional, continental to global. Work involves mathematic modeling, large-scale data development, data-model integration, geospatial and statistical analysis. Overall, it can serve as a powerful tool for assessing the provision of ecosystem goods and service, and identifying better management practices and mitigation options for a sustainable earth.
