GCAM Configuration Generator

This project generates GCAM (Global Change Analysis Model) scenario configuration files by combining base templates with SSP-specific components across multiple parameter combinations.

Files Overview

Core Files

• functions.py - Contains all the classes and functions for generating GCAM configurations
• 20250927 Config files generation.ipynb - Jupyter notebook interface for running the generator
• configuration_reuse100.xml - Base template configuration file
• SSP1_config.xml to SSP5_config.xml - SSP-specific component files

Configuration Files

Base Template

• configuration_reuse100.xml - Core GCAM configuration template that serves as the foundation for all generated scenarios. Contains default settings for all GCAM components including energy systems, land use, water, emissions, and solver configurations.

SSP Component Files

The SSP (Shared Socioeconomic Pathways) files were extracted from batch_GCAM_REF.xml:

• SSP1_config.xml - Sustainability pathway components
• SSP2_config.xml - Middle of the road pathway components
• SSP3_config.xml - Regional rivalry pathway components
• SSP4_config.xml - Inequality pathway components
• SSP5_config.xml - Fossil-fueled development pathway components

Naming Convention

Generated files follow the pattern: {SSP}_{RCP}_{Tech}_{Supply}_{Allocation}_PR{Rate}.xml

Examples:

• SSP1_2p6_Basic_L_Mkt_PR0.xml
• SSP4_6p0_Tech_H_Reg_PR100.xml

Output Directories

• config_sample_subset/ - Contains test subset configurations (typically 2-10 files for testing)
• configs_ensemble_complete/ - Contains full ensemble configurations (all 2,400 possible combinations)
