Ecosystem Dynamics and Forecasting

Ecosystem: We study the forest and freshwater ecosystems upon which society depends

Dynamics:  We model how ecosystems change over time in response to land-use, climate change, atmospheric deposition, and management.  We measure carbon, water, and energy exchange between ecosystems and the atmosphere using eddy-covariance and biometeorology sensors.

Forecasting:  We predict the future of ecosystems by combining observations and ecosystem models using statistical techniques.

Projects

Ecological Forecasting Initiative Research Coordination Network (DEB-1926388)

Lead PI of an NSF sponsored 5-year project that is leading workshops, conferences, and collaborative software development to address the following objectives:

  1. Define community standards and best practices for developing, sharing, and archiving forecasts and models
  2. Increase the number and diversity of NEON-enabled (National Ecological Observatory Network) forecasts by developing and hosting the NEON Ecological Forecasting Challenge
  3. Create educational materials to empower scientists at all career stages to forecast using NEON data products
  4. Support the creation of software to produce NEON-enabled forecasts at intensive and collaborative coding-focused workshops
  5. Align forecast outputs and decision support with the needs of forecast users at mission-driven agencies to guide decision making, and
  6. Synthesize forecasts to examine how limits to forecastability vary across ecological systems and scales.
