An updated map of the sea surface temperature (SST) of the world's largest inland sea is generated every day as part of ESA's Medspiration project, with an unprecedented spatial resolution of two square kilometres, high enough to detect detailed features like eddies, fronts and plumes within the surface temperature distribution.
In addition to ensuring you plunge into warm water, knowledge of SST is important for weather forecasting and is increasingly seen as a key indicator of climate change. The idea behind Medspiration is to combine data from multiple satellite systems to produce a robust set of sea surface data for assimilation into ocean forecasting models of the waters around Europe and also the whole of the Atlantic Ocean.
Like thermometers in the sky, a number of different satellites measure SST on an ongoing basis using state-of-the-art instruments. Medspiration utilises data from ESA’s Envisat and Meteosat-8, the United States’ National Oceanic and Atmospheric Administration (NOAA) polar orbiters, the Japanese’s Space Agency-NASA Tropical Rainfall Measuring Mission and the AMSRE instrument onboard NASA's Aqua.
The temperature of the surface of the ocean is an important physical property that strongly influences the transfer of heat and sensible and latent fluxes between the ocean and the atmosphere.
And because water takes a long time to warm up or cool down the sea surface functions as an enormous reservoir of heat: the top two metres of ocean alone store all the equivalent energy contained in the atmosphere.
Overall results from the Medspiration project also feed into an even more ambitious scheme to combine all available SST data into a worldwide high-resolution product, known as the Global Ocean Data Assimilation Experiment (GODAE) High-Resolution Sea Surface Temperature Pilot Project (GHRSST-PP).
ESA not only initiated Medspiration as the European contribution to the overall GHRSST-PP effort, but the also funded a GHRSST International Project Office, located at the Hadley Centre for Climate Prediction and Research, a part of the UK Met Office located in Exeter.
Under ESA contract, the Medspiration operations are carried out by the EUMETSAT Sea and Ice SAF at the Meteo-France's Centre for Space Meteorology and the French Research Institute for Exploitation of the Sea (IFREMER) under the leadership of the Southampton Oceanography Centre.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
