<p>Cars. Cows. Oil and natural gas leaks. The list of what is polluting our atmosphere and contributing to global warming is long and varied. And if we want to solve this problem, being able to accurately measure what’s happening is key. </p><p>NIST is contributing to this critical measurement challenge in many ways. One approach being pursued uses a Nobel Prize-winning technology called a <a href="/topics/physics/optical-frequency-combs" data-entity-type="node" data-entity-uuid="d0f3e23a-9ded-41b4-b75e-df0223888093" data-entity-substitution="canonical" title="Optical Frequency Combs">frequency comb</a>, which is a very precise “ruler” for measuring exact colors of light. A group of NIST scientists have been adapting the frequency comb to make these crucial measurements. <a href="/news-events/news/2018/03/mobile-dual-comb-device-significantly-improves-methane-leak-detection" data-entity-type="node" data-entity-uuid="022c02fb-6ac7-4b67-a710-43e18a13cc30" data-entity-substitution="canonical" title="Mobile ‘Dual-Comb’ Device Significantly Improves Methane Leak Detection">In 2018</a>, they successfully demonstrated a way to use two frequency combs to continuously and cost-effectively monitor leaks of methane (CH<sub>4</sub>) and other trace gases with extreme precision and over large areas. <a href="/news-events/news/2021/06/nist-laser-comb-systems-now-measure-all-primary-greenhouse-gases-air" data-entity-type="node" data-entity-uuid="124e9039-1994-4d7b-97d6-b2abdf63d9b8" data-entity-substitution="canonical" title="NIST Laser ‘Comb’ Systems Now Measure All Primary Greenhouse Gases in the Air">In 2021</a>, those researchers upgraded the instrument so that it could simultaneously measure three airborne greenhouse gases — nitrous oxide, carbon dioxide and water vapor — plus the major air pollutants ozone and carbon monoxide. This dual-comb technology could help in understanding and monitoring emissions of the heat-trapping greenhouse gases implicated in climate change, as well as in assessing urban air quality. </p><p>Three of these scientists — NIST Fellow Nathan Newbury and scientists Ian Coddington and Kevin Cossel — are being recognized for their work. They are all finalists for a 2022 Samuel J. Heyman Service to America Medal, known as a "Sammie," in the science, technology and environment category. The citation recognizes them for developing “a revolutionary system to detect and stop methane gas leaks from oil and gas production facilities as well as identify other pollutants that are major contributors to global warming.”</p><p>Below, we talk with the finalists about their work and what’s next for the technology. </p><h2>What made you think about using a frequency comb for methane gas detection? Or, in other words, what was the genesis of this work? </h2><p><strong>NATE:</strong> We were developing the basic technique of dual-comb spectroscopy and realized that it was very well suited to a precision experiment and could probably work well outside of the laboratory. It was glaringly clear even back then that climate change was upon us and that measuring methane and other greenhouse gases was an important thing to do. So, we decided to go for it and see if we could use this new technique over long open-air paths to measure methane, and carbon dioxide and water. </p><p>This first open-path experiment was done by sending light out of the so-called penthouse of Building 1 on the NIST campus, which was being used by the public affairs office actually at the time and, despite its fancy name, was terrible for office space. It makes for a great lab space, though, since there are windows out of which you can send frequency comb light across Boulder. The experiment worked well and really started us all on that path. </p><p>It is very important to emphasize there was a much larger team working on this project than just the three of us from the beginning through to the present, including Greg Rieker, while he was at NIST, Brian Washburn (leading the agricultural measurement

<p><strong>NATE:</strong> Brian Washburn is leading an effort to apply the same technology to <a href="/news-events/news/2021/03/nist-agricomb-measures-multiple-gas-emissions-cows" data-entity-type="node" data-entity-uuid="279030c2-6276-46a4-b18f-9fafcb6441ce" data-entity-substitution="canonical" title="NIST ‘Agricomb’ Measures Multiple Gas Emissions From … Cows">agricultural emissions of greenhouse gases</a>. Brian has already done some really interesting initial measurements and has identified a number of ways this technology can help reduce the significant carbon emissions associated with agriculture. Additionally, measurements could guide new agricultural practices allowing carbon to be captured in soil. </p><p>Also, we have moved into sensing in the mid-infrared, which can potentially help with air quality issues.</p><p><strong>IAN:</strong> We are also working with NIST colleagues to develop calibration-free absolute measurements of carbon dioxide and methane. Much of the work so far has been high-precision relative measurement but linking to an absolute scale will allow for greater comparison of dual-comb instruments across the globe and over decades, as well as the ability to directly calibrate carbon monitoring satellites.</p><h2 class="nist-block__title">Related Video</h2><figure class=" align-center nist-video" role="group">
