Making the invisible visible

Because pollution varies so heavily from street to street, and by the hour, it’s critical to forecast it with the greatest accuracy and spatial resolution. Leveraging the best of machine learning and atmospheric sciences, we’ve built an API that does just that. Our live air quality data and hourly forecasts make the air more transparent, and empower businesses, researchers and organizations to build solutions that help people breathe better air.

Why choose Plume API

From earth view to street view

Drawing on over 12,000 monitoring stations and cutting-edge modelling capabilities that take into account numerous datasets including weather data, population density, land use data and road network data, we provide air quality data for any location - down to street level in major cities.

A.I. meets environmental science

We combine machine learning with atmospheric models to deliver real-time and hourly forecast air quality data.

The hardware-enabled air quality API

Thanks to our smart air quality tracker Flow®, we will aggregate hyperlocal data from our community of urban citizens — ensuring unmatched precision.

Data tailored to your needs

Get insights on the main pollutants harming people’s health (PM2.5, PM10, O3, NO2, CO, SO2) with absolute concentration levels and your local air quality scale — alongside our Plume Index. Other measurements available include pollen (Grass, Tree and Weeds) and UV.

Highly accurate and reliable

Already powering large scale client applications - as well as our air quality forecast app, the Plume Air Report, our platform shows best-in-class accuracy and reliability.

How our technology works

We collect the latest pollution levels (which are in average 2-3 hours late) from over 12,000 monitoring stations and 80 public agencies around the world.

Our quality control features filter for errors, outliers, station downtime (e.g. maintenance) etc.

We source local atmospheric data (wind, temperature, atmosphere, etc.) to track their influence on pollution levels in your city.

Our team of data scientists analyzes local specifics such as geographical features and human activities — because every city is unique.

We develop AI algorithms and atmospheric models that turn this giant amount of data into hourly forecasts. This means you get truly real-time data, and predictions for the next 24h.

We deliver developer-friendly data, in absolute concentration levels, in your local AQI and in our own Plume Index.
