DISCOVER-AQ: Reaching for the Sky with Student Citizen Scientists

As school reopens with bouquets of newly-sharpened yellow pencils (as they say in the movies), even recent graduates like me get swept up in the excitement: a new season of academic discovery! This fall, an EPA partnership with NASA is helping the next generation of students experience the thrill of air quality research first-hand.

During this mission, named DISCOVER-AQ (the “AQ” stands for “air quality”), our team will employ the help of young “citizen scientists” in Houston to test new compact sensor technologies for measuring ozone and nitrogen dioxide air pollutants at the earth’s surface.

Citizen science is a style of research that encourages inexperienced and even very young participants to help with professionally organized research projects. Volunteers collect simple field data that would be difficult for the lead researches to gather without many hands. If projects inspire awe, discovery, and insight along the way, well, that was part of the plan.

The multi-year DISCOVER-AQ project uses airplanes and ground-based instruments to help scientists better understand how to measure and forecast air quality globally from space. My colleagues recently installed compact ground-based devices for the third of four DISCOVER-AQ field missions. The devices—small enough to be held in one hand—were placed at eight Houston area public schools. EPA-trained teachers will lead their students in operating the new air monitors. Elementary, middle, and high school students will contribute the data they collect to the EPA research team, helping professional scientists develop needed updates to methods of standardizing air quality measurements across the country.

EPA DISCOVER-AQ researcher Dr. Russell Long reports, “The school’s principals and teachers are very excited about what’s going on; they say it’s a great opportunity for their students.” These educators have already requested that EPA scientists working with the schools to ensure high quality data will double as guest speakers for the classes, helping kids make the connection between book science and research in action. The scientists are thrilled to participate. We are fine-tuning a set of air, climate, and energy activities to support the project’s science concepts in classrooms.

NASA partners also see the project as a unique opportunity for sharing their work with young people. In the NASA component of the project, pilots will fly aircraft fitted with air monitoring equipment at scheduled times over the schools. The flight data will be matched with ground-based data to help researchers measure air pollutants that permeate the air column. Students will be able to talk with the pilots during these coordinated fly-overs while they watch the planes approach on a tracking app and then zoom overhead!

DISCOVER-AQ is science far beyond the laboratory. The experience will be unmatched for hundreds of students who may not have considered science as a captivating career before. These student scientists can feel proud they’re contributing to fundamental research to help NASA and EPA protect human health and the environment. I look forward to hearing what the students find out!

    NASA and EPA : Omg…… Fantastic !

    It’s amazing the students give feedback and proud to collect AQ data for research program. All stakeholders could be benefit and they begin to save this planet. Good Luck Dana and Team…….!!!!!

    I hope the air around the world can be checked in all cities by NASA

    This is interesting — What are the sensors and can they be purchased and used for classes or citizen scientists routinely? Thanks.

      The sensors being evaluated with student participants in the DISCOVER-AQ study are part of ongoing EPA research focused on advancing air pollution monitoring technology. The sensors, called “CairClip”, are commercially available. EPA is not directly distributing the sensors to the public for independent research or citizen science. In Houston the EPA will assess how some new technologies compare to current air quality measurements developed and used by EPA, often called Federal Reference Methods (FRM). The purpose is to test the accuracy of the new compact sensor technologies compared to established methods currently used to monitor air quality. In addition EPA scientists will assess improvements to the established air quality measurement technologies for the air pollutants ozone (O3) and nitrogen dioxide (NO2). EPA provides Teacher Resources and Lesson Plans covering air and other environmental topics—I hope you’ll take a look! http://www.epa.gov/students/teachers.html
