The CryoSat validation programme took another important step forward on Wednesday with the official handover of a unique set of data that had been collected by the intrepid Dutch Polar Explorer Marc Cornelissen on behalf of ESA during his recent expedition to the North Pole.
In March this year, Marc Cornelissen left Cape Arctichesky in northern Russia to lead the Pole Track 2005 expedition on a 1,000 km ski trek to the geographic North Pole. Along the way, the expedition team deployed mobile weather stations to transmit meteorological data, and collected a valuable set of snow depth measurements following a protocol that had been developed with ESA.
"While snow depth information holds the key to producing accurate maps of ice-thickness change over time with CryoSat, there are surprisingly few of these basic measurements readily available," says Malcolm Davidson, ESA CryoSat Validation Manager. "As a rule, people dont spontaneously spend weeks on end on the ice measuring this parameter. Marc Cornelissens careful measurements of snow thickness during his expedition are thus very valuable indeed. The data will now be analysed by scientists participating in ESAs CryoSat calibration and validation programme."

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
