Dr. Bill Parton’s primary research activities center around the study of greenhouse gas emissions, predictive modeling to help stakeholders (i.e. ranchers and farmers) make informed decisions on how the climate will affect them in the coming year, and how land use change effects the carbon cycle. He is the primary author of the ecosystem models: Century, DayCent, ForCent, and is currently working on the development of PhotoCent (see model descriptions). Additionally, he is working on the Grass-Cast Project which is a predictive above-ground grassland plant production (ANPP) model that uses current weather data, the DayCent model and precipitation forecasts to help ranchers predict what the grass production will be for the grazing season. Dr. Parton has published over 150 papers and book chapters. He is fellow for the Ecological Society of America and the American Geophysical Union and was honored as a Resident Distinguished Ecologist at Colorado State University. He has had numerous projects funded by NSF, USDA, DOE, EPA and NIH.
