This $929,221 federal Project Grant awarded by the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) aims to enhance understanding of the terrestrial carbon cycle across North America. The project will generate a new data tool that integrates ground-based measurements, satellite data, and mathematical models to analyze carbon pool and flux variability in response to environmental factors like temperature, precipitation, and land use. Key objectives include evaluating model reliability, identifying data collection gaps, and improving predictability of carbon dynamics at multiple spatial and temporal scales. The research team will collaborate with the U.S. Forest Service to incorporate the data products into federal carbon accounting efforts and seek certification for use in voluntary carbon markets. The award also supports training opportunities for graduate and undergraduate students, including an effort to increase American Indian/Alaskan Native participation in STEM fields. The project period runs from August 1, 2024 to July 31, 2028.
