From: Flow Analysis at the Snow Covered High Altitude Catchment via Distributed Energy Balance Modeling
Parameter | Symbol | Adjustment | Detail |
|---|---|---|---|
Coordinate System | COORDSYS | UTM | Coordinate system used to specify locations in the model |
Model Boundary Condition | CHANGE_BC | Neumann | Two boundary conditions are available at snow-atmosphere interface. Neumann or Dirichlet |
Roughness length | ROUGHNESS_LENGTH | 0.002 | Mass of an element that is neither changed by phase changes nor densification |
Mode of model | SW_MODE | Incoming | Based on available data. Incoming short wave radiation or both incoming short and longwave radiations. |
Enforced measure snow height | ENV_Meas_Snow_Depth | False | Uses measured precipitation or snow height as input |
Canopy detail | CANOPY | False | Canopy detail at study area or no vegetation |
Input Precipitation data treatment | PSUM | Accumulate | PSUM is accumulated at hourly temporal resolution or raw. |
Atmospheric Stability | ATMOSPHERIC_STABILITY | Monin-Obukhov44 | Various stability-correction schemes are available to consider temperature inversions on snow and glacier surface. |
Geothermal heat flux | GEO_HEAT | 0.06 | Depends on type of soil |
Soil albedo Snow albedo Ice albedo | Soil_Albedo Snow_Albedo Ice_Albedo | 0.2–0.3 | Depends on type of soil Computed at each time step by the model Fixed58 |
