A one-dimensional model, which was presented in Yamazaki (2001) to
estimate water and energy fluxes over a ground in particular in
intensely cold regions, has been applied to GAME-Siberia plain taiga
sites in 2000. In GAME-Siberia, 2000IOP has been carried on left-side
bank and right-side bank of Lena river near Yakutsk. For left-side bank,
it is simulated to larch and pine forest sites. Model parameters except
plant area index and soil parameters in the pine site are tentatively
set to the same as 1998 simulation at the larch site. Diurnal and
seasonal changes of fluxes are simulated reasonably. However, for the
larch site, heat flux into the ground is less and sensible heat is more
through the simulated period compared with 1998. It is found that
discrepancy of latent heat between both sites in spring because of the
differece of deciduous or evergreen forest. In snowmelt season, the snow
cover disappears earlier in the model calculation. This tendency is same
as the result of 1998. It will be studied what kind of parameters
defines energy and water fluxes with use of the model including
right-side bank (young larch forest).
