Spatial and temporal analysis of carbon cycle for boreal forests in Alaska

Project Year: 2004

We evaluate the carbon cycle in boreal forests in Alaska, where the climate warming has been observed, by using tower flux measurements, terrestrial biosphere model, and satellite remote sensing.

Simulating carbon and water cycle at larch forests in East Asia

Project Year: 2008

Process-based terrestrial biosphere models were tested to larch forests at several AsiaFlux sites, and used to identify important environmental factors on the carbon and water cycle in both temporal and spatial scale.
