Air Tracker

Home › Resources › Air Tracker

Description

Mapping tool showing air monitoring locations and the locations that contribute to air quality for a set of large cities in the U.S.

Questions this resource can help answer

What are the locations that contribute to air quality at locations in my city?

How do I use this resource?

Click on one of the blue circles to go to a specific city. Within the city map, you can see monitors in green, with wind directions show in blue arrows. You can click anywhere within the dotted line boundaries to see the locations that impact air quality at the spot, based on wind directions. You can also create a heat map showing the likelihood that pollution in that spot comes from different directions and locations. If you click on a green monitoring location, you can also get data on recent pollution measurements for PM2.5.

Pro tips

Heat maps take a bit of time to generate, so patience is recommended.

Methodology

Air Tracker uses air quality data from regulatory monitors and air sensor networks, combined with wind speed and direction data from EPA and state networks. Source directions are modeled using the Stochastic Time Inverted Lagrangian Transport Model.

NOAA Air Resources Laboratory

The ARL site is a scientific research and modeling portal. Its mission is to improve the Nation’s ability to protect human and ecosystem health by studying the physical and chemical processes occurring from the soil up to about 2–3 miles in the atmosphere. It is the birthplace of the HYSPLIT model, the global standard for tracking the movement of air parcels.

AQview: Community Air Quality Viewer

Air quality maps, trends viewer, a downloadable tool and lab data. From the website: "AQview is a community-focused air quality data portal bringing together government and community-led air monitoring data to a single platform. Our primary goal is make it easier to access, understand, and use air quality data collected from the wide range of monitoring efforts occurring across California."

ModelTool

Air Quality through Urban Actions (AQUA) tool

The AQUA tool is an easy-to-use excel spreadsheet model that city staff can use with minimal guidance. It uses population, exposure, health and economic cost data, as well as epidemiologic evidence to help users calculate how emission changes can benefit local air quality and health.
