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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
