What is BreezoMeter's Air Quality Index?

Post first published December 11, 2014, updated May 5, 2017. 

While we now offer many product features, from pollen counts to 4 day forecasting, the BreezoMeter Air Quality Index remains our core feature, included in all plans and used by most if not all of our clients. 

How, and why, did we come up with the index? 

Variations in National Air Quality Indexes (AQIs)

Almost every country in the world calculates an Air Quality Index (AQI) - a scale of numbers that represents the current or daily air quality levels in different areas. AQIs are based on local air quality standards and pollutants concentrations specific to each country.

For example, while in US standards 54 ppb (parts per billion) of Nitrogen Dioxide (NO2) gas defines moderate air quality (1 hour average), in Israel 250 ppb of NO2 defines the same AQI (30 min average). Moreover while the United States defines six different levels of AQI, Israel defines four and Hong Kong five (see below).

Thus there is a great variety of "air quality languages". Each AQI, of each country, is different and that can be quite confusing for end users, as well as complex in terms of product development. That is why we created a new, unique and uniform air quality index – the Breezometer AQI that provides a clear and intuitive way to read and understand real-time air quality information.

Introducing the BAQI

Breezometer AQI (BAQI) has been developed by our R&D team based on academic research, national AQIs, and other important considerations. The BAQI scale goes from 0 = "poor" to 100 = "excellent" with 5 color-coded categories of equal lengths, as you can see below:

The efforts we've put in to build a worldwide Air Quality Index have translated into satisfied customers, who are able to display our global AQI, &/or national Air Quality Indexes, as we always provide both, in each and every country we cover.

 

We partnered with BreezoMeter for their unparalled accuracy, ability to scale globally, and simple-to-use API
