Short Summary

This paper announces CCART v3.0, the first fully modular, open-source release of the Climate Catastrophe Analysis & Risk Toolkit for India, designed to assess and analyze climate-related hazards and risks.

Objective

• To provide a modular, open-source software toolkit (CCART v3.0) for comprehensive climate catastrophe analysis and risk assessment specifically tailored for India.

Study Configuration

• Spatial Scale: India (national and district boundaries)
• Temporal Scale: Historical and synthetic scenarios for cyclone and flood hazards, enabling climate-conditioned risk assessment.

Methodology and Data

• Models used:
  • Cyclone module (v2 engine): CLIMADA-based hazard model, DLNA-aligned calibration.
  • Flood module (v1 engine): Flood Severity Index (FSI) generation.
  • Vulnerability module: Modular, hazard-specific curves.
  • Calibration module: Synthetic and historical workflows.
• Data sources:
  • Flood module: CHIRPS (Climate Hazards Group InfraRed Precipitation with Station data) ingestion.
  • Exposure module: Wealth data and district boundaries.
  • Historical and synthetic data for cyclones and floods.

Main Results

• The release of CCART v3.0, a fully modular and open-source Climate Catastrophe Analysis & Risk Toolkit for India.
• The toolkit includes distinct modules for cyclones (v2 engine), floods (v1 engine), exposure, vulnerability, and calibration.
• It features a clean, reproducible architecture with module-level READMEs and does not track outputs or heavy data in version control.

Contributions

• This is the first fully modular and open-source release of a comprehensive toolkit for climate catastrophe analysis and risk assessment specifically for India.
• It provides a reproducible framework for analyzing historical and synthetic climate hazards, exposure, and vulnerability.
• The toolkit integrates CLIMADA-based hazard modeling and CHIRPS data ingestion, offering a robust platform for risk assessment.
