Airborne Carbon in the Mountains Experiment (ACME)

The Airborne Carbon in the Mountains Experiment is the first aircraft field campaign of a program supported by the NSF Biocomplexity Program and NASA Interdisciplinary Science. It is taking place in the Front Range of the Rocky Mountains in Colorado. The goal of the project is to understand carbon dynamics in montane forest regions by developing new methods for estimating carbon exchange at local to regional scales. More...

Carbon Data - Model Assimilation (C-DAS)

The Carbon Data-Model Assimilation (C-DAS) project is intended to bring observationalists and modelers together to form an integrated approach to improving our understanding of the global carbon cycle. Observations of the carbon cycle are being taken at increasingly high spatial and temporal resolutions. To understand what this data impies about the working of the underlying carbon cycle, new model-data fusion techniques are required. We have developed a variational data assimilation approach to efficiently process the new data. Atmospheric fluxes from the sea and land biosphere may be estimated efficiently at fine time/space resolutions. Alternatively, the data may be used to optimize key parameters in the carbon cycle models themselves,to improve their predictive capabilities. More...
