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: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Im Focus: Autonomous 3D scanner supports individual manufacturing processes

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).

Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
