A library to convert between AQI value and pollutant concentration (µg/m³ or ppm)

Project description

A library to convert between AQI value and pollutant concentration (µg/m³ or ppm) using the following algorithms:

• United States Environmental Protection Agency (EPA)

• China Ministry of Environmental Protection (MEP)

Install

$pip install python-aqi Usage Library Convert a pollutant to its IAQI (Intermediate Air Quality Index): import aqi myaqi = aqi.to_iaqi(aqi.POLLUTANT_PM25, '12', algo=aqi.ALGO_EPA) Get an AQI out of several pollutant concentrations, default algorithm is EPA: import aqi myaqi = aqi.to_aqi([ (aqi.POLLUTANT_PM25, '12'), (aqi.POLLUTANT_PM10, '24'), (aqi.POLLUTANT_O3_8H, '0.087') ]) Convert an IAQI to its pollutant concentration: import aqi mycc = aqi.to_cc(aqi.POLLUTANT_PM25, '22', algo=aqi.ALGO_EPA) Command line List supported algorithms and pollutants: $ aqi -l
aqi.algos.epa: pm10 (µg/m³), o3_8h (ppm), co_8h (ppm), no2_1h (ppb), o3_1h (ppm), so2_1h (ppb), pm25 (µg/m³)
aqi.algos.mep: no2_24h (µg/m³), so2_24h (µg/m³), no2_1h (µg/m³), pm10 (µg/m³), o3_1h (µg/m³), o3_8h (µg/m³), so2_1h (µg/m³), co_1h (mg/m³), pm25 (µg/m³), co_24h (mg/m³)

Convert PM2.5 to IAQI using EPA algorithm:

$aqi aqi.algos.epa pm25:12 39 Convert pollutants concentrations to AQI using EPA algorithm: $ aqi aqi.algos.epa pm25:40.9 o3_8h:0.077 co_1h:8.4
