Miasma - Local Air Quality 4+

- shows publicly available air quality data for your locality (chosen automatically based on IP address, or manually by you)
- gives 1 hour weather forecast (including air quality data & pollen prediction, where available globally)
- lists potential pollution source data, such as electrical generation, aircraft overhead & road traffic (availability of data varies globally)
- shows and help make sense of climate change data (CO₂ emissions & global warming)
- menu bar icon changes colour to match current AQI PM₂.₅ conditions (and can show AQI numerically too)
- each data source is clickable to launch further information to see trends & forecasts
- notifies if the AQI quality worsens beyond a threshold you set, or separately if it improves below a threshold you set (ideal to help decide if you want to go for a run or not!)
- shows historical Air Quality (and compares to World Health Organisation guidelines) for SmartCitizen & PurpleAir users
- updates its metrics every 30 minutes or 15 minutes
- simple graphics help make sense of the numbers given
- free open source software

Data is sourced from PurpleAir (only publicly available sensors), RapidAPI, global-warming.org/US NOAA, WAQI/AQICN.org, SmartCitizen, Sensor.Community, Electricity Maps, OpenSky, Telraam & Tomorrow.io.
