| In comparison to BCC_AVIM1.0, two improvements were implemented in BCC_AVIM1.5: environment dependent phenology of vegetation, soil character and soil moisture dependent threshold of temperature for soil freezing/melting. In BCC_AVIM1.0, dates for leaf onset in spring and leaf senescence in autumn for deciduous vegetation and the associated loss rate are prescribed according to current climatology of each plant functional type (Ji, 1995). Similar to Canadian Terrestrial Ecosystem Model (CTEM) (Arora,...... |
more...BCC_AVIM 1.0
| BCC_AVIM1.0 is originated from the Atmosphere and Vegetation Interaction Model (AVIM, Ji, 1995) and includes three sub-modules: biogeophysical, ecophysiological and soil carbon-nitrogen dynamical modules. A modified biogeophysical framework with 10-layer soil and at most 5-layer snow is almost the same as that in the NCAR Community Land Model version 3.0 (CLM3, Oleson et al., 2004). Since the snow cover fraction (SCF) is underestimated in CLM3 which is similar to that in BATS (Yang, 1997),, the scheme...... |
