Hourly atmospheric air quality index for fine dust of 2.5 microns fraction in settlements of Ukraine

Hourly calculations of the atmospheric air quality index according to the formula NowCast (US EPA) for the main air pollutant - fine dust of 2.5 microns fraction in settlements of Ukraine.

Primary air quality indicators are measured by monitoring stations established by residents of settlements, independent projects, organizations, local authorities, etc.

The SaveEcoBot system collects and aggregates all of these indicators, and each hour calculates AQI PM2.5 according to the NowCast formula (US EPA) for each station. After that, the arithmetic mean of the index is calculated for the corresponding settlements.
