Gather and document major functional requirements for a user-friendly, interactive, and accessible dashboard that integrates and harmonizes real-time and historical data from air quality sensors and regulatory monitors. Develop an initial map-based dashboard for selected pollutants to confirm approach, look/feel (UI/UX), navigation, performance, accessibility (e.g., for PM2.5 from PurpleAir sensors and regulatory monitors) Develop map-based dashboard for all data sources/pollutants. Implement interactive visual elements such as graphs, and charts showing AQI, NowCast, and multiple temporal averages. Develop configurable banners and alerts for public notifications; enable user alert subscriptions. Implement QA/QC processes, including bad data filtering, correction factor application, push alerts and quality flagging. Provide filtering options for pollutants, date ranges, locations, and monitor types. Develop secure, scalable system for long-term data retention and fast access.
