Biogeochemistry Team: D. Graham (ORNL) is an expert in microbial biochemistry, methanogenesis, and microbial evolution; he will lead this team.
Data Management Team: The NGEE Arctic data management team will be co-led by T. Boden (ORNL) and G. Palanisamy (ORNL). Tom will be responsible for managing the data team, interacting with the NGEE science team, and gathering input and feedback from end users. Giri will oversee the design and development of the data system architecture including data interoperability and systems operations.
Hydrology/Geomorphology Team: C. Wilson (LANL) will lead this science focus. Researchers from LANL will primarily focus on the application of tracers and stable isotopes to quantify lateral hydrologic connectivity, the partitioning of precipitation between runoff, perennial ponding, and evapotranspiration as well as the development of model evaluation datasets. Researchers from UAF will focus on the design, deployment, and analysis of meteorologic, hydrologic, and thermal process observations and their representations in process models and the development of model evaluation datasets.Researchers from LBNL will focus on the geophysical and experimental characterization of subsurface material properties and the assimilation of these data into model initialization datasets and the development of THM constitutive relationships.
Independent Observations for Integrated Model Evaluation Team: M. Torn (LBNL), who is a principal investigator (PI) of the ARM Carbon project that includes three eddy covariance systems, will lead this team and many of the tasks.
Landscape Characterization Team: J. Rowland (LANL) will lead this team working to provide accurate characterization of the landscape and translation of data collected in the field and laboratory into useful datasets, process algorithms, and model parameters requires classification of the landscape into discrete units based on ecological, hydrological, and geological properties.
Multiscale Modeling Team: P. Thornton (ORNL) will lead this team, with primary responsibility for coordinating modeling efforts across scales and across process domains, as well as overall coordination between modeling team and process science teams. Two deputy modeling leads have also been designated for each of the three scales and for each of the three process domains.
Hydrology/ Geomorphology Process Modeling Across Scales: W. Bolton (UAF), an expert in spatially distributed hydrologic modeling in Arctic landscapes, and J. Rowland (LANL), an expert in Arctic geomorphology and hydrology, will serve as deputy leads.
Biogeochemistry Process Modeling Across Scales W. Riley (LBNL), a biogeochemist who studies and simulates carbon and nitrogen cycles, coupled land-surface and atmospheric exchange, and climate change, and C. Koven (LBNL), a land surface modeler with expertise on Arctic methane biogeochemistry, will serve as deputy leads.
Vegetation Dynamics Modeling Across Scales: D. Hayes (ORNL) and A. D. McGuire (UAF), experts on Arctic vegetation and carbon cycling, will serve as deputy leads.
Climate-Scale Modeling Across Process Domains: C. Koven (LBNL) and P. Thornton (ORNL) will serve as deputy leads.
Intermediate-Scale Modeling Across Process Domains: S. Painter (LANL), an expert in subsurface flow and transport modeling, and A. Liljedahl (UAF), an expert in Arctic watershed hydrology, will serve as deputy leads.
Fine-Scale Modeling Across Process Domains: R. Mills (ORNL), an expert in parallel computation numerical methods and subsurface hydrology, and V. Romanovsky (UAF), an expert in permafrost geophysics will serve as deputy leads.
Representativeness and Scaling Team: Perform representativeness analysis within the Barrow domain to determine sampling locations and fine-scale measurement representativeness.
Site Characterization Team: S. Hubbard (LBNL), who has extensive experience in field experimentation and shallow subsurface characterization using remote datasets, will lead this team and will lead and will participate in several associated tasks.
Vegetation Dynamics Team: R. Norby (ORNL) will lead this team effort.
