NASA measuring Tropical Storm Yasi's inland rainfall from space

Tropical Cyclone Yasi has continued moving through inland Queensland, Australia and has weakened to a tropical depression today. NASA and JAXA's TRMM satellite passed over Yasi as it continued to drop moderate to heavy rainfall.

On February 3 at 0300 UTC (Feb. 2 at 10 p.m. EST/1 p.m. Australia local time) Tropical cyclone Yasi continued over land as a tropical storm. Yasi's maximum sustained winds were near 60 knots (69 mph/111 kmh). It was moving west-southwest near 20 knots/23 mph/37 kmh). It was located about 200 miles (321 km) southwest of Cairns, Australia near 19.3 South and 143.4 East.

The TRMM satellite flew above the cyclone at 0339 UTC (Feb. 2 at 10:39 p.m. EST/1:39 p.m. Australia local time) collecting data on rainfall rates. Yasi was still dropping moderate to heavy rain over Australia in an area southeast of the Gulf of Carpentaria. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches per hour. Red areas are heavy rainfall at almost 2 inches per hour. Credit: NASA/SSAI, Hal Pierce

Just 39 minutes after the position of Yasi's center was determined, the Tropical Rainfall Measuring Mission (TRMM) satellite flew above the cyclone at 0339 UTC (Feb. 2 at 10:39 p.m. EST/1:39 p.m. Australia local time) collecting data on rainfall rates. Yasi had weakened to tropical storm strength but TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data reveal that the storm was still dropping moderate to heavy rain over Australia in an area southeast of the Gulf of Carpentaria.

Just about an hour later, another NASA satellite passed over Yasi capturing the massive size of the strom in a visible image. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard NASA's Aqua satellite captured data on Yasi at 04:15 UTC (Feb. 2 at 11:15 p.m. EST/2:15 p.m. Australia local time. The center of Yasi had already moved inland and the eye of the storm had become obscured by clouds.

The Australia Bureau of Meteorology (ABoM) website has been updating residents of Yasi's movement and affects. To see the ABoM's radar, visit:

At 9:30 a.m. EST (14:30 UTC) on Feb. 3 (or 12:30 a.m. Australia local time on Feb. 4) Yasi was approaching the border of the Northern Territory and had weakened into a tropical depression. The ABoM noted that isolated thunderstorms, heavy rains, flash flooding and damaging winds with gusts greater than 48 knots (55 mph/90 kmh) are possible in the western interior of Queensland.

Im Focus: Etching Microstructures with Lasers

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...
