Hyper-Local Air Quality (AQI) & Outdoor Activity Planner
Inspect station pollutant concentrations, sub-indices across national standards (India CPCB, US EPA 2024, UK DEFRA DAQI), data freshness, official alerts, and gated outdoor window comparisons without medical profiling.
How the Hyper-Local Air Quality (AQI) & Activity Planner Works
Inspect live monitoring station pollutant concentrations (PM2.5, PM10, O3, NO2, SO2, CO), physical mass units, station distance, and observation timestamps before comparing sub-indices under India CPCB NAQI, US EPA 2024 AQI, or UK DEFRA DAQI scales.
Key Inputs & Verification Data
- Locality search / manual country + timezone + 0.05-deg grid or opt-in session geolocation
- Measured pollutant readings (PM2.5, PM10, O3, NO2, SO2, CO) evaluated under jurisdictional breakpoints
- Non-diagnostic outdoor activity preferences (type, duration, exertion, daypart)
Observation vs. Forecast Separation & Non-Medical Guidance
Station measurements remain strictly separated from nowcast or spatial model estimates and official regional weather/air alerts (such as UK-AIR DEFRA and US NWS). The planner collects zero personal medical diagnoses or symptoms and abstains whenever forecast skill or spatial agreement is too low for window comparisons.
Built on privacy minimisation: never asks for medical diagnoses, symptoms, or medications. Exact GPS coordinates are quantized in browser session to ~0.05-deg grids before gateway requests and never logged or persisted.
Frequently Asked Questions
Why do CPCB NAQI, US EPA AQI, and UK DAQI report different numbers for the same PM2.5 reading?
Each jurisdiction uses distinct statutory breakpoints, pollutant weights, and averaging intervals (24-hour vs 1-hour or sliding nowcast), so raw concentrations and index versions must be reported together.
Can this AQI tool diagnose asthma or provide medical clearance?
No. It provides public environmental exposure context only and does not replace physician or official public-health advisories.
