Terrestrial carbon
fluxes are an important factor for the studies of global warming. This study
focuses on estimating a fluctuation
of the terrestrial carbon fluxes in the
Tokai region, Japan.
The local biosphere model used calculates carbon, water, and heat fluxes, and
required some climate and vegetation parameters as inputs. The model was
operated in 2000-2004 using meteorological data and MODIS data products.
We estimated spatial distributions in heat
and carbon fluxes at spatial resolution of 1*1 km, and validated an
adaptability of the model using measured data at the Takayama flux-site. As a
result, estimated GPP and heat fluxes had a good relationship to measured data.
We can precisely check on the accuracy of the model to estimate the
spatial and temporal patterns of the terrestrial carbon fluxes.
