In the nearly 50 years of meteorological satellite observations, the data have increasingly been used to complement research satellite data for purposes of observing climate processes and monitoring change.
However, many of the early research and meteorological satellites were either not designed for climate-quality measurements, or were not succeeded at the end of their lifetimes. The resulting patchwork of quality data has required extraordinary scientific effort to yield credible climate information.
Karl, who serves as both director of NOAA's Climatic Data Center and all of NOAA's climate services, will discuss how a new Climate Data Record (CDR) Project within NOAA will address the challenge of delivering regular climate data and information, following rigorous scientific standards, which are necessary to understand climate variability and change.
The Project will stitch together and reprocess various archives of heritage satellite data, using proven state-of-the art methods, and will address future data sources, including the National Polar-orbiting Operational Environmental Satellite System (NPOESS) and the NPOESS Preparatory Project (NPP) spacecraft.
The NOAA CDR Project will largely execute its activities through competitive grants and contracts, and will emphasize interagency coordination in moving technologies from research programs to operations at the National Climatic Data Center and in other parts of NOAA.
It is designed for sustained implementation, such that mature CDRs can be subjected to further improvements crafted through a parallel basic research programs as new measurements and observing systems come on-line. Numerous examples will be provided to show the importance of a well-defined and managed NOAA CDR Project.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
