The Tropical Rainfall Measuring Mission or TRMM satellite can estimate rainfall rates from its orbit in space and that data is used to create a rainfall analysis and calculate total rainfall for weather events in the tropics. NASA used TRMM and other satellite data to calculate rainfall from Atlantic hurricanes Fay and Gonzalo.
Tropical Storm Fay battered Bermuda on October 12, 2014 and became a hurricane after passing the island. The following Friday powerful Hurricane Gonzalo passed directly over the island on Friday October 17, 2014 causing flooding and damage to many structures.
The remnants of Gonzalo also pounded the British Islands with winds exceeding 70 mph causing the death of at least one person.
An analysis of rainfall was conducted on Fay and Gonzalo as they moved through the central Atlantic Ocean and over Bermuda. The analysis was based on near real time TRMM-based precipitation estimates (TMPA) that were produced by merging data from several satellites.
The analysis showed that Gonzalo generated several areas over the Atlantic Ocean where rainfall totals topped 12 inches (300 mm). Fay's maximum rainfall was between 4 and 8 inches (100-200 mm).
The rainfall estimates have been developed at the NASA Goddard Space Flight Center in Greenbelt, Maryland by the precipitation research team. The type of data used in this analysis is expected to be superseded by a Global Precipitation Measurement (GPM) mission product in late 2014.
TRMM is managed by NASA and the Japan Aerospace Exploration Agency. For more information about TRMM, visit: trmm.gsfc.nasa.gov. For more information about GPM, visit: www.nasa.gov/gpm.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
