App for Android/iOS [How to USE it]

How do you know how polluted the air is on an everyday basis? To answer it, most of us rely on privately run programs that may or may not give us accurate data and details. To be able to assess the right air quality and to know more about fires in your area or any other area, you can refer to the app. From this discussion, learn more about the app.

What is app?

With Airnow, the new app on-site, you can get all your air quality-related data easily. The site is recently redesigned for the users and also provides you with an app available on Google.

Why is Airnow special than other available apps and website air quality meters?

The reason for Airnow to be a prominent one is that it uses the US official Air Quality Index (AQI). It is a color-coded index metric and partners with National Oceanic and Atmospheric Administration (NOAA), National Park Service, U.S. Environmental Protection Agency, Centers for Disease Control (CDC), NASA, tribal states, and local air quality organizations.

Airnow gets the data directly from the national centers monitoring air quality in a particular country and they place it up for display on their site.

It can forecast air quality, provide you with the current data, inform you about fire conditions, and also informs you about Canada and Mexico air quality details.

How does works?

Each and every hour data flows from 1300 ozone and 300 PM2.5 across 44 states alongside the District of Columbia and Canada.

  • After this stage, almost 100 state, local, and other federal agencies acting as funnels collect the data.
  • They then submit the data to DMC using the file transfer protocol.
  • After this step, the ozone and PM data gets loaded in the Oracle Relational database.
  • Through automatic quality control, the quality of the data is checked.
  • With the help of QC checks, minimum and maximum thresholds are determined alongside the change rate, and other inconsistencies are assessed and analyzed.
  • Different thresholds and QC check parameters are set.
  • Next, air quality is converted to AQI.
  • Half an hour after the passage of every hour, local, regional, and national maps are generated for ozone and PM2.5.
  • These maps are next available at every site which uses them including the Airnow site.

Is accurate? app is very accurate and there is no doubt about how accurate it is due to the process in place to generate the data.


For people who need to know the daily air quality, this app could relieve your stress largely. Read the details to understand better about the app.
