Greenhouse gases: The measurement challenge

18.08.2011
The continuing increase in the level of carbon dioxide and other "greenhouse gases" in the Earth's atmosphere has been identified as a cause for serious concern because it may radically accelerate changes in the Earth's climate.

Developing an effective strategy for managing the planet's greenhouse gases is complicated by the many and varied sources of such gases, some natural, some man-made, as well as the mechanisms that capture and "sequester" the gases. A new report sponsored by the National Institute of Standards and Technology (NIST) focuses on one of the key challenges: defining and developing the technology needed to better quantify greenhouse gas emissions.

The new report, "Advancing Technologies and Strategies for Greenhouse Gas Emissions Quantification," is the result of a special workshop in the NIST Foundations for Innovation series, convened in June 2010, to bring together greenhouse gas experts from government, industry, academia and the scientific community to address the technology and measurement science challenges in monitoring greenhouse gases.

A wide variety of techniques are used for measuring greenhouse gas emissions and, to a lesser extent, the effectiveness of "sinks"—things like the ocean and forests that absorb greenhouse gases and sequester the carbon. The problem is that developing an effective global strategy for managing greenhouse gases requires a breadth of measurement technologies and standards covering not only complex chemical and physical phenomena, but also huge differences in scale. These range from point sources at electric power plants to distributed sources, such as large agricultural and ranching concerns, to large-scale sinks such as forests and seas. Satellite-based systems, useful for atmospheric monitoring, must be reconciled with ground-based measurements. Reliable, accepted international standards are necessary so governments can compare data with confidence, requiring a lot of individual links to forge an open and verifiable chain of measurement results accepted by all.

The report identifies and discusses, in detail, four broad areas of opportunity for technology development and improvement:

Advanced science and technology for reliably quantifying greenhouse gas emissions, regardless of geography, sector or source;

Accurate and reliable quantification of distributed carbon sources and sinks;

Consistent, standardized methods for measurable, reportable and verifiable greenhouse gas emissions data; and

Integration of ground-based (bottom-up) and remote atmospheric observation (top-down) methods.

Copies of the new report are available at the Website for the 2010 June meeting, "Greenhouse Gas Emissions Quantification and Verification Strategies Workshop" at http://events.energetics.com/NISTScripps2010/downloads.html, along with additional materials from the workshop.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
