NASA Puts Tropical Storm Dorian in the Infrared Spotlight

The newest tropical storm to form in the Atlantic was put in NASA's "infrared spotlight." NASA's AIRS instrument uses infrared imaging to analyze tropical cyclones and captured an image of newborn Tropical Storm Dorian.

NASA's Atmospheric Infrared Sounder instrument also known as AIRS, flies aboard the Aqua satellite. AIRS uses infrared light and shined that light on Tropical Storm Dorian on July 25 at 03:29 UTC (11:29 p.m. EDT, July 24).

The AIRS instrument aboard NASA's Aqua satellite captured this infrared image of Tropical Storm Dorian on July 25 at 03:29 UTC (11:29 p.m. EDT, July 24). Strongest storms and heaviest rains are around the center and in a band of thunderstorms south of the center with cloud top temperatures near -63F/-52C (purple).

Infrared data helps determine temperature, such as the cloud top and sea surface temperatures. AIRS data revealed that Dorian's strongest storms and heaviest rains were around its center and in a band of thunderstorms south of the center. Those areas had cloud top temperatures near -63F/-52C, indicating very high thunderstorms.

Forecasters at the National Hurricane Center kept a close eye on Dorian over the last 24 hours as it traversed cooler sea surface temperatures, and survived. Dorian is now moving over and toward warmer waters.

The official position of Tropical Storm Dorian at 11 a.m. EDT (1500 UTC), was about 1,800 miles (2,900 km) east of the northern Leeward Islands, near 16.0 north and 35.9 west, according to the National Hurricane Center or NHC. The NHC noted that Dorian's maximum sustained winds were near 60 mph (95 kph) and some fluctuations in intensity are expected in the next couple of days. The tropical-storm-force winds extend outward up to 60 miles (95 km) from the center, making Dorian about 120 miles (190 km) in diameter.

Dorian was moving toward the west-northwest near 17 mph (28 kph) and that general motion is expected to continue today, followed by a gradual turn toward the west on Friday, July 26. The estimated minimum central pressure is 999 millibars.

The NHC expects Dorian to continue to move west-northwest across the Atlantic.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
