Library

NOTE: Different standards use different units for calculating AQI, use the appropriate units to get correct results. Examples for getting the units for each standards as well as unit conversion is avaiable (examples soon!)

Convert a pollutant to its IAQI (Intermediate Air Quality Index):

import aqicalc as 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 aqicalc as 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 aqicalc as aqi
mycc = aqi.to_cc(aqi.POLLUTANT_PM25, '22', algo=aqi.ALGO_EPA)
