Interactive dashboard of Madagascar's temperature and rainfall trends (2005–2024) — Streamlit, Plotly, NASA POWER data # Madagascar Climate Dashboard Interactive dashboard presenting temperature and precipitation trends across Madagascar's 23 regions between 2005 and 2024, built from NASA POWER satellite data. ## Live demo madagascar-climate-dashboar… ## Features - Interactive choropleth map (temperature / precipitation) - Monthly evolution with linear trend, filterable by region and period - Comparative ranking of all 23 regions - Dry season vs rainy season comparison - Filterable data table with CSV export ## Tech stack - Python, Pandas, NumPy - Streamlit (interface) - Plotly (interactive visualizations) - Geographic data: geoBoundaries (ADM1, Madagascar) ## Run locally ```bash pip install -r requirements.txt streamlit run app.py ``` ## Project structure ``` ├── app.py # Main Streamlit application ├── requirements.txt └── data/ ├── madagascar_climate_processed.csv └── madagascar_regions.geojson ``` ## Note on regions Madagascar has officially had 23 regions since 2021 (Vatovavy-Fitovinany was split in two). The climate data distinguishes all 23 regions throughout the dashboard, except on the map, where Vatovavy and Fitovinany are merged (average of the two) because standard public geographic boundaries have not yet been updated to reflect this split. ## Data source NASA POWER Project, parameters `T2M` (temperature at 2m) and `PRECTOTCORR` (corrected precipitation), monthly resolution, 2005–2024.
