Chinas rainy season has led to serious flooding in the north-east and south of the country. A joint Chinese-European team is gathering Envisat radar imagery of the developing situation to give the authorities a way to swiftly assess affected areas and plan their responses.
Summer flooding is nothing new in these regions of the Peoples Republic of China (PRC), though this year it is proving particularly severe, with more than 800 casualties countrywide and 2.45 million people forced to evacuate their homes. However this seasons flooding is being monitored in near real-time by ESAs Envisat Advanced Synthetic Aperture Radar (ASAR) sensor, which can acquire imagery in both day and night and in all weathers.
This activity is taking place as part of ESAs Dragon Programme of cooperation with the National Remote Sensing Centre of China (NRSCC) within the Ministry of Science and Technology of the PRC. These Envisat images are a means for the authorities to identify floodwater extent and coordinate mitigation efforts, and should be a foretaste of things to come – next season the aim is that a full near real-time monitoring service should be operational.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
