Visualize Air Quality with RETIGO

By Kayla Schulte

EPA scientists developed  “RETIGO.”

EPA scientists developed “RETIGO.”

Today, more and more researchers and citizens are collecting their own air quality data using lower cost and portable instruments. While air quality monitoring technology has expanded into the hands of the individual with the creation of apps and small mobile sensors, the means to explore the measurements in-depth has been fairly restricted—until now.

EPA scientists recently developed the Real-Time Geospatial Data Viewer, or “RETIGO,” a free, web-based tool that allows users to visualize air quality data derived from any number of monitoring technologies.

RETIGO puts the power of analysis in the user’s hands with its interactive platform and easy-to-navigate interface. The user simply uploads their air quality data to the online tool system to visualize and interact with small to large data sets over space and time. Data collected while driving, riding a bicycle, or walking along a planned route can be explored on a map interface and also shown on several other graphs.

Interested in giving RETIGO a try for yourself? EPA researchers are conducting four training webinars in November where you will be able to learn more, pose questions, and chat with them and other participants. The interactive component will be conducted by both text and audio (you will need to use a computer microphone or connected headset for live audio).

To find out how you can use this innovative visualization tool to explore your measurements and discover how factors such as nearby pollution sources and wind direction can affect your observations, join one of the following webinars:

  • Monday, November 17, 9:00 am to 10:00 am, EST
  • Monday, November 17, 11:00 am to 12:00 pm, EST
  • Wednesday, November 19, 9:00 am to 10:00 am, EST
  • Wednesday, November 19, 3:00 pm to 4:00 pm, EST

Launching RETIGO is just one of the many ways EPA encourages environmental awareness by inviting individuals to explore their surroundings through innovative science. Join use later this month to learn more!

A New Frontier for Air Sensors 2014

By Dustin Renwick

Compact air quality sensor fits in the palm of your hand.

The wearable market has expanded its product line—from smart glasses and smart watches to dozens of different fitness tracker wristbands and T-shirts that interact with the world around you.

What you don’t see in these gadgets is the tiny technologies that make it possible for your T-shirt to light up or for you to tap your wrist and see how many calories you’ve burned.

Similar to how computers shrunk from the size of rooms to the size of your front pocket, sensors have also been developed in ever decreasing dimensions.

One of the major applications for EPA: sensors that measure air quality. Agency researchers and others can use these portable, real-time sensors in the environment to gain a more intricate picture of what’s happening in our communities.

We’ve hosted a competition won by a design for a wearable sensor that estimates a person’s exposure to air pollution. EPA grants fund broad cookstove research, some of which includes the use of air sensors to measure pollution from indoor cookstoves.

Last fall, EPA collaborators published a seminal paper on the sensor revolution in a top journal, Environmental Science & Technology. The journal received more than 5,400 submissions in 2013 on a variety of topics, and EPA’s research won first runner-up for best feature paper.

One of the most important parts of this field of study is the diversity of people interested in the work.

Next week, we’ll hold an air sensors workshop to spark more discussions and continue this important work advancing innovative air sensor technologies by bringing together scientists, policy experts, technology developers, data analysts, and leaders from government, industry, and community groups.

To learn more about the opportunities and challenges that air sensors present, register for the webcast of our workshop on June 9-10.

We’ll live tweet the event from @EPAresearch using #AirSensors.
