Typhoon Phanfone packed heavy rainfall as it brushed over Japan and NASA's TRMM satellite identified where the rain fell. That data was used to make a map of rainfall totals.
The Tropical Rainfall Measuring Mission or TRMM satellite has the ability to calculate rainfall rates within storms as it orbits around the Earth's tropics from space. TRMM data can also be used to create rainfall maps that show how much rain has fallen over given areas.
Phanfone was a powerful super typhoon with sustained wind speed estimated at 130 knots (150 mph) as it approached Japan but had weakened to a category one typhoon with sustained winds of about 70 knots (81 mph) as is passed near Tokyo.
The TRMM- based, near-real time Multi-satellite Precipitation Analysis (TMPA) conducted at the NASA Goddard Space Flight Center in Greenbelt, Maryland has been measuring the distribution of precipitation over the tropics since TRMM's launch in 1997.
TMPA based rainfall totals were calculated for the period from September 28 to October 6, 2014 during which Phanfone formed east of Guam and traveled to Japan. The typhoon dropped rainfall over much of Japan but rainfall was particularly heavy near Phanfone's track along the southeastern coast of the islands.
The analysis indicated that Phanfone dropped the greatest amount of rainfall in central Japan west of Tokyo where rainfall totals greater than 275 mm (10.8 inches) were found. This analysis found some rainfall totals above 300 mm (11.8 inches) over the Pacific Ocean southeast of Japan.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
