pyradtran.config.load_config

pyradtran.config.load_config(config_path: str | Path | None = None) → SimulationConfig

Load and merge the three-layer configuration.

Resolution order (later wins):

1. Package defaults (config/clean_simulation.yaml).

2. User master config (~/.pyradtran/config.yaml).

3. config_path (the simulation-specific YAML).

Parameters:

config_path (str or pathlib.Path, optional) – Simulation-specific YAML. When None, only layers 1 + 2 are used.

Return type:

SimulationConfig

Raises:

• FileNotFoundError – If config_path is given but does not exist.

• ConfigurationError – If the merged dictionary cannot be converted to SimulationConfig.
