Alfred Wegener Institute inherits the radiation data archive WRMC

07.07.2008
From the mountains to the coast - the Alfred Wegener Institute for Polar and Marine Research based in Bremerhaven inherits the World Radiation Monitoring Center, Switzerland

The international archive for radiation data, the World Radiation Monitoring Center (WRMC), provides climate research with high-precision meteorological series of measurements.

After a term of fifteen years at the Swiss Federal Institute of Technology Zurich (ETHZ), the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association ensures the successful continuity and enhancements of this unique archive. These data serve the monitoring of the climate, the surveillance of anthropological influence on the earth's surface as well as the improvement of climate forecasts.

The International Panel on Climate Change (IPCC) dealt with the compilation of contemporary knowledge on climate research for the first time at the end of the eighties. It was discovered, among other things, that baseline energy conversion of solar radiation as well as thermal radiation of the earth's surface and the clouds were not sufficiently known. A global Baseline Surface Radiation Network (BSRN) was demanded to correct this shortcoming.

The demands for accuracy concerning these monitoring stations were very high, so that only ten stations worldwide participated in the beginning. Among these were the observatories at the Neumayer Station in the Antarctic as well as the Koldewey Station on Spitsbergen in the Arctic, both run by the Alfred Wegener Institute. In the meantime, 43 monitoring stations worldwide are entering their data into the network.

The core of the World Radiation Monitoring Center (WRMC) is its central data archive. It was developed at the ETHZ under the direction of Prof. Ohmura in 1992 and contains all accompanying meteorological observations, which are necessary for the interpretation of the radiation measurements, available at minute intervals. Among these are vertical profiles of air temperature and humidity gained by means of weather balloons, observations of clouds and cloud heights.

Surface radiation - which influences the climate decisively - is estimated area-wide by means of satellites. Accuracy is improved by comparison with direct measurements of the World Radiation Monitoring Center.

Climate models rely on procedures which provide baseline radiation, too. These computations of radiation are verified and optimized with the data provided by the World Radiation Monitoring Center. Furthermore, trend analyses are possible by means of these measurements, since some stations have been measuring continually for fifteen years. First results currently point to a slight increase of radiation originating from the sun, most probably as a result of improved politics of air pollution control.

The archive will be officially opened by Dr Gert König-Langlo, meteorologist and director of the WMRC at the Alfred Wegener Institute in the framework of the 10th BSRN workshop from July 7th to 11th in De Bilt, the Netherlands. You can find further information under: http://www.bsrn.awi.de

The Alfred Wegener Institute carries out research in the Arctic and Antarctic as well as in the high and mid latitude oceans. The institute coordinates German polar research and makes available to international science important infrastructure, e.g. the research icebreaker "Polarstern" and research stations in the Arctic and Antarctic. AWI is one of 15 research centres within the Helmholtz Association, Germany's largest scientific organization.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
