(1) MODEL AND VERSION:
Full model name: STOMATE
Host institution: LSCE
Key references: Viovy, 1996, Ducoudré, 1993
(2) MODEL TYPE (E.G. ECOSYSTEM, BIOGEOGRAPHY, DGVM:
DGVM
(3) PRIMARY MODEL PURPOSE:
Coupled Hydrology, Carbon and Vegetation Dynamics
(4) MODELING APPROACH:
physiological / mechanistic
(5) RESOLUTION (SPATIAL, TEMPORAL):
Spatial resolution is given by forcing (climatology) typically 1 degree. Temporal resolution is 30 minutes for hydrology, energy and GPP, daily for carbon processes and annual for vegetation dynamics.
(6) SPATIAL AND TEMPORAL SCALE(S) AT WHICH THE MODEL RESULTS SHOULD BE CONSIDERED:
Site scale and continental/global scale
Diurnal scale for hydrology, energy and GPP, daily cycle for carbon
(7) PROCESSES AND PROCESS COMPONENTS SIMULATED (E.G. CARBON: GPP, NPP, NEP):
Carbon:
GPP, NPP, allocation, phenology, autothrophic respiration, litter and soil dynamics, heterotrophic respiration, NEP
Water:
STOMATE is coupled to SECHIBA, which is a comprehensive land surface model. Leaf level and canopy integration of GPP is done in SECHIBA to insure consistency of GPP and transpiration.
a)Soils (simple bucket, saturated/unsaturated flow, controls on water movement through the profile, etc.):2 layers with variable depth
b)Energy balance: (e.g. latent, sensible heat, aet, pet): Latent and sensible heat
c) Snow: Yes
d) Order of water balance: (e.g. incoming water is first evaporated from plant/soil surface, then infiltration, transpiration, runoff): Interception loss, then bare soil and plant transpiration, then infiltration and runoff
Nitrogen: Diagnosed from soil carbon, temperature and humidity
(8) SIMULATED RESERVOIRS:
Carbon:
a) Vegetation: 8 pools
b) Litter: 4 pools
c) SOC: 3 pools
Nitrogen:
a) Vegetation:
b) Litter:
c) SON: 2 pools
Soil water:
2 layers
(9) CALIBRATION VARIABLE(S) AND METHOD:
Phenology calibrated on satellite data
(10) SCALING OF THE PROCESSES TO THE GRID CELL:
Canopy integration of GPP, LAI,...?Subgrid vegetation distribution (mosaic)
(11) DISTURBANCE (FIRE, GRAZING, HARVEST, TREE REMOVAL, ETC.):
Fire
(12) VEGETATION I/O (E.G. POTENTIAL, ACTUAL):
Potential (calculated by the model) or actual (from satellite)
(13) INPUT DRIVERS (CLIMATIC, SITE, VEG, SOILS) AND RESOLUTION (E.G. DAILY, MONTHLY) REQUIRED FOR MODEL INITIALZATION:
30 minutes resolution of air surface temperature, precipitation, incoming radiation, specific humidity, wind speed, soil types and vegetation cover (if vegetation dynamic is not calculated).
(14) ADDITIONAL COMMENTS:
STOMATE is coupled to SECHIBA for hydrology and energy balance and to LPJ, for vegetation dynamics. It can run without LPJ (prescribed vegetation).
