Pacific Northwest National Laboratory set to launch million-dollar mobile atmospheric-measuring station on worldwide tour to fill data gaps in global climate models

Balloon-borne sounding system. Check. Micropulse lidar. Check. Infrared thermometer. Check. Eddy correlation flux measurement system. Eddy correlation flux measurement system?! Check already.

These and a dozen other instruments and computer- and maintenance-shop-jammed cargo containers make up the ARM Mobile Facility, or AMF, the world’s most sophisticated moveable, atmospheric-measuring suite. In early February, the AMF will be carefully packed and shipped from the Department of Energy’s Pacific Northwest National Laboratory, where the system was designed, assembled and is being tested, to Point Reyes National Seashore, north of San Francisco.



There it will be reassembled and take in the local atmosphere, literally, for nine months before heading to sub-Saharan Africa , in time for the 2006 monsoon season in Niger . The instruments are designed to withstand temperatures from minus-40 to plus-120 degrees Fahrenheit, said PNNL’s Kevin Widener, AMF chief engineer and supervisor for the testing.

The station is designed to measure the physical properties of literally anything that blows over and the heat that radiates from clouds and from the ground, said Widener, who, with Tom Ackerman, a Battelle fellow at PNNL, designed and put together the $1.4 million system at the behest of the DOE Office of Science.

The AMF is part of DOE’s Atmospheric Radiation Measurement (ARM) Climate Research Facility, which already includes fixed sites in Oklahoma , the North Slope of Alaska and the Tropical Western Pacific region near northeastern Australia . The AMF expands the ARM program’s reach into additional climatic regions, providing critical information now missing in models.

Besides PNNL’s engineering team, key collaborators in the AMF project include Argonne , Brookhaven and Los Alamos national laboratories. For more information, see http://www.arm.gov/ and http://www.arm.gov/sites/amf.stm .

PNNL ( www.pnl.gov ) is a DOE Office of Science laboratory that solves complex problems in energy, national security, the environment and life sciences by advancing the understanding of physics, chemistry, biology and computation. PNNL employs 3,800, has a $600 million annual budget, and has been managed by Ohio-based Battelle since the lab’s inception in 1965.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
