In this branch, I have documented the current radiation parameter naming patterns to support future harmonisation efforts addressing duplicates. Here you will find:

1. radiation_parameters_report.txt
   A comprehensive inventory of radiation parameters in sample_config.yml, organised by category with line numbers, parameter names, full YAML paths, and descriptions.

2. CSV Files (5 files)

• radiation_emissivity.csv (21 parameters)
• radiation_albedo.csv (34 parameters)
• radiation_transmissivity.csv (2 parameters)
• radiation_absorptivity.csv (2 parameters)
• radiation_reflectivity.csv (2 parameters)

Each CSV contains: Parameter Name | YAML Path | Context/Category

To the best of my knowledge, all radiation parameters have been included, but I’d appreciate it if you could review and confirm before we move forward in sorting out what duplicates are.
