climasus4r - Integrated Analysis Toolkit for Health, Climate, and Environmental Data in Brazil: Reproducible Workflows for Climate-Health Research

climasus4r is a comprehensive R toolkit for integrated analysis of health, climate, and environmental data in Brazil. The package automates the entire data pipeline: (1) importing and cleaning health data from the Brazilian Unified Health System (SUS) across six systems (SIM, SIH, SINAN, SIA, CNES, SINASC); (2) integrating climate data (INMET, ERA5), air quality (AQI), environmental data (MapBiomas), and socioeconomic indicators (IBGE); (3) performing flexible spatiotemporal aggregation at multiple scales; (4) constructing reproducible analytical pipelines (RAPs) that ensure transparency and replicability. Designed for researchers studying climate-health interactions, environmental vulnerability, and adaptation strategies in the Brazilian context. Supports multilingual output (Portuguese, Spanish, English) and parallel processing for large datasets.
