CitizenWeather is an open-source initiative dedicated to democratizing weather data and empowering communities with hyperlocal climate intelligence. We believe everyone should have access to accurate, real-time weather information and the tools to make data-driven decisions about their environment.

To create accessible, open-source weather technology that enables individuals, communities, and organizations to understand and respond to climate patterns with confidence and precision.

• 🔓 Open — Open source, open data, open collaboration
• ♿ Accessible — Technology for everyone, regardless of technical skill
• 🌱 Sustainable — Climate-conscious development and operations
• 🤝 Community-Driven — Built by and for the community
• 📊 Data-First — Accurate, transparent, trustworthy information
