python-aqi 0.2

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

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)

Usage

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)
