Create Default Calibration Settings for airGR Models

set_airGR_par.Rd

Generates a list of default calibration settings for a specified model from the airGR family. This includes parameter bounds and optimizer configurations for DEoptim, malschains, and hydroPSO.

Usage

set_airGR_par(model)

Arguments

model

A string specifying the airGR model (e.g., "GR4J", "CemaNeigeGR4J"). For a complete list see table in vignette("model_overview").

Value

A list containing:

  • lower, upper – numeric vectors of parameter bounds.

  • nof_param – number of parameters.

  • DEoptim, malschains, hydroPSO – optimizer settings.

  • has_snow_module – logical indicating whether the model includes a snow module.

Details

The function uses CreateCalibOptions to extract parameter bounds and sets default configurations for several optimizers. It also detects whether the model includes a snow module based on the model name.

Note

This function only supports models from the airGR family. An error is thrown otherwise.
