By pairing a sleek new air sampler designed at the University Corporation for Atmospheric Research (UCAR) with a diode laser from SpectraSensors, Inc., researchers have hit on a technology that can capture highly accurate atmospheric water vapor data during routine commercial flights. The data will benefit researchers and forecasters, who need more frequent, accurate measurements at various altitudes worldwide to improve weather forecasts and monitor climate change.
Currently water vapor data is gathered by an older style of sensor using a thin-film capacitor. These sensors are launched on weather balloons every 12 hours from stations around the country. Satellites also gather water vapor data, but at low vertical resolution. The WVSS II aboard commercial flights will gather data more often, at higher vertical resolution, and at lower cost than satellites and balloons.
"Water vapor sounds boring," says recently retired UCAR scientist Rex Fleming, who designed the innovative air sampler, "but its essential to almost everything that happens in the atmosphere." Better water vapor data from around the U.S. and the world can improve forecasts of thunderstorms, microbursts, turbulence, fog, ceiling visibility, rotating wakes from other aircraft, snow and ice storms, and year-round precipitation, he says.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
