The Climate Absolute Radiance and Refractivity Observatory (CLARREO) Mission includes a fleet of satellites tentatively scheduled for launch later this decade that will gather data for long-term climate projections. The CLARREO mission will provide an accurate climate record of the complete spectrum of energy that Earth reflects and radiates back into space, measurements that should provide a clearer understanding of the climate system.
NIST’s role will focus on the calibration of the instruments aboard CLARREO satellites, as well as on the accuracy that the sensors must meet. The measurements need to be characterized to far greater accuracy—from two to 10 times better, depending on the wavelength of light in question—and detector standards need to be developed for the far infrared region of the spectrum. NIST will also help NASA improve its own capabilities in instrument calibration. The collaboration was finalized in a Space Act Agreement on Feb. 4, 2010.
CLARREO, led by NASA Langley Research Center in Hampton, Va., is now among NASA’s top-priority missions because of its high ranking by the National Research Council, which designated CLARREO one of its four “Tier One” missions when it evaluated proposals in 2007. NASA is allocating $270,000 for NIST’s contributions to the project this year.
The mission is part of a longer-term effort to establish global long-term climate records that are of high accuracy and traceable to the international system of units (SI). The CLARREO satellites and other instruments will be calibrated against international standards based on SI, so that observations from different times and locations can be compared usefully, creating a more reliable record of long-term climate trends.

Gravitational wave kicks monster black hole out of galactic core

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...
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...

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.

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.
