7.1. Model Inputs

• Files required to run SUEWS

• The data are needed for every grid (can be any shape) area in the domain to be modelled.

7.1.1. Model Physics options

• RunControl

• the selection of which submodels are to be used

• choose after the other decisions

7.1.2. Forcing data

• Meteorological variables needed

7.1.2.1. Data Sources

• Observations

• Climate data e.g. ERA5, projections

• Coupled Model e.g. WRF

7.1.2.2. Height consideration of the forcing data

• Several heights need to be considered

7.1.3. Site Information

• Site parameters

7.1.4. Initial Conditions

• Initial conditions

• Conducting a model spinup for a number of years allows for the influence of the conditions selected to begin with to become less critical.

• Key conditions to consider

  • leaf area index (leaf-on, leaf-off) - this is critical for evaporation

  • soil moisture state - this is critical for evaporation

• less critical

  • surface state (as long as modelling for many days) as these will change rapidly.

  • it is easy to just set this to be dry (e.g. summer) or wet (e.g. if rain has just occured)

• meteorological variables

  • These can be determined from a wide range of data (e.g. the same source as your forcing data)

• snow conditions

  • This needs to be done very carefully for a short model run. A long model run starting from snow-free conditons would ensure that the snow accumulation occurs at the right time etc
