AEME Inputs

aeme-inputs.Rmd

Summary

Inputs for AEME are designed to similar to most standard data inputs used in lake ecosystem modelling.

Lake

Lake inputs include:

Meteorological Data

Meteorological data requirements for lake modelling are similar to those used in most lake ecosystem models. The following meteorological variables are required for AEME:

  • Air temperature
  • Shortwave radiation
  • Wind speed
  • Rain
  • Either relative humidity or dew point temperature
  • Either mean sea level pressure or station pressure

The following meteorological variables can be derived from the required variables:

  • Dew point temperature
  • Relative humidity
  • Precipitation vapor pressure
  • Wind u and v components
  • Cloud cover
  • Longwave radiation

Inflows and Outflows

Inflows

Inflows are important for lake hydrodynamics and water quality. Inflows can be specified as a time series of flow rates (m3/s) and temperature (C). They can also include nutrient and sediment concentrations if the biogeochemistry model is being used.

One of the most important features of configuring an inflow is ensuring that the variables are in the correct units and that the variable names match those specified in the key_naming data frame.

Parameters

Being able to specify the parameters of the model is crucial for the simulation. Parameters can be stored in a data frame within the aeme object. The parameters in this data frame are used to update the model configuration files and/or update the meteorological data (e.g. scaling wind factor) and/or update the inflow/outflow data (e.g. scaling inflow factor).
