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: pm25, pm10, o3_8h, o3_1h, co, so2, no2
aqi.algos.mep: pm25, pm10, o3_8h, o3_1h, so2_24h, so2_1h, no2_24h, no2_1h, co_24h, co_1h

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:8.4

Convert pollutants concentrations to AQI using EPA algorithm, display IAQIs:
