1. General Modeling Guidelines

To simplify navigation through the Model customization section, we offer a summary as follows:

1. Basic customization: Provides guidance on customizing the default configuration file to suit specific modeling needs, including specifying the country/region of interest and enabling essential data downloads.

2. Running the model: Explains the process of running the model using the Snakemake workflow management tool, selecting a solver, and ensuring successful optimization.

3. Model Validation: Outlines procedures for validating data obtained from PyPSA-Earth, including simulation procedures, reference data sources, and advanced validation examples.

4. Setup Copernicus API: Describes the steps to access the Copernicus Climate Data Store for building custom cutouts, including registration, setting up the CDS API key, and considerations for cutout generation.

Each section provides essential information for effective model usage and customization, ensuring accurate and reliable results.
