Introduction
In the face of climate change, data-driven decision-making has become essential. The West African Science Service Centre on Climate Change and Adapted Land Use (WASCAL) plays a crucial role in providing climate-related research and solutions. To enhance research capabilities, we developed a scalable and efficient data infrastructure tailored to WASCAL’s needs. This article presents the architecture, technologies, and benefits of this infrastructure.
Purpose of the WASCAL Data Infrastructure
The goal of the WASCAL Data Infrastructure is to centralize, process, and analyze climate-related data across West Africa. It enables researchers, policymakers, and institutions to access real-time and historical climate data for informed decision-making. Key objectives include:
- Data Centralization: Aggregating climate data from multiple sources into a unified system.
- Advanced Analytics: Supporting AI and machine learning models for climate predictions.
- Accessibility & Security: Ensuring authorized users can retrieve and analyze data efficiently.
- Scalability: Adapting to the growing volume of climate data over time.
Technologies Used
To achieve high performance and reliability, the WASCAL Data Infrastructure integrates several modern technologies:
- Database Management: PostgreSQL with PostGIS for geospatial data handling.
- Cloud Storage & Computing: AWS S3 & EC2 for scalable storage and computing resources.
- Data Processing Pipelines: Apache Kafka and Apache Spark for real-time and batch data processing.
- API Development: FastAPI for a lightweight and high-performance RESTful interface.
- Data Visualization: Dashboards built with Plotly, Streamlit, and D3.js for interactive insights.
- Security & Authentication: OAuth 2.0 and JWT for secure access management.
