New airborne GPS technology for weather conditions takes flight


First demonstration captures key meteorological data, offers potential of better hurricane forecasting 

GPS technology has broadly advanced science and society’s ability to pinpoint locations and motion, from driving directions to tracking ground motions during earthquakes. A new technique stands to improve weather models and hurricane forecasting by detecting precise conditions in the atmosphere through a new GPS system aboard airplanes.

A new GPS system aboard airplanes could improve weather models and hurricane forecasting by detecting precise conditions in the atmosphere. “GISMOS” (GNSS [Global Navigation Satellite System] Instrument System for Multistatic and Occultation Sensing) communicates with satellites to define details of the atmosphere.

The first demonstration of the technique, reported this month in the American Geophysical Union journal Geophysical Research Letters, is bringing the project’s leaders closer to a goal of broadly implementing the technology in the near future on commercial aircraft.

Current measurement systems that use GPS satellite signals as a source to probe the atmosphere rely on GPS receivers that are fixed to the ground and can’t measure over the ocean, or they rely on GPS receivers that are also on satellites that are expensive to launch and only occasionally measure in the regions near storms.

The new system, used by geophysicist Jennifer Haase of the Scripps Institution of Oceanography in La Jolla, Calif., and her colleagues, captures detailed meteorological readings at different elevations in targeted areas of interest, such as where hurricanes might develop over the Atlantic Ocean.

“This field campaign demonstrated the potential for creating an entirely new operational atmospheric observing system for precise moisture profiling from commercial aircraft,” said Haase. “Having dense, detailed information about the vertical moisture distribution close to the storms is an important advancement, so if you put this information into a weather model it will actually have an impact and improve the forecast.”

“Satellite-based measurements are now regularly used for weather forecasting and have a big impact, but airplanes can go beyond satellites in making observations that are targeted right where you want them,” noted Eric DeWeaver, program director in the National Science Foundation’s (NSF) Division of Atmospheric and Geospace Sciences, which funded the research.

The paper details a 2010 flight campaign aboard NSF aircraft and subsequent data analysis that demonstrated for the first time that atmospheric information could be captured by an airborne GPS device. The instrumentation, which the scientists labeled “GISMOS” (GNSS [Global Navigation Satellite System] Instrument System for Multistatic and Occultation Sensing), increased the number of atmospheric profiles for studying the evolution of tropical storms by more than 50 percent.

“We’re looking at how moisture evolves so when we see tropical waves moving across the Atlantic, we can learn more about which one is going to turn into a hurricane,” said Haase. “So being able to look at what happens in these events at the early stages will give us a lot longer lead time for hurricane warnings.”

“This is another case where the effective use of GPS has the potential to improve the forecast and therefore save lives,” said Richard Anthes, president emeritus of the University Corporation for Atmospheric Research, which currently runs the satellite based GPS measurement system called COSMIC (Constellation Observing System for Meteorology, Ionosphere, and Climate).

While the current GISMOS design occupies a refrigerator’s worth of space, Haase and her colleagues are working to miniaturize the technology to shoe box size. From there, the system can more feasibly fit onto commercial aircraft, with hundreds of daily flights and a potential flood of new atmospheric data to greatly improve hurricane forecasting and weather models.

The technology also could improve interpretation of long-term climate models by advancing scientists’ understanding of factors such as the moisture conditions that favor hurricane development.

Im Focus: Climate study finds evidence of global shift in the 1980s

Planet Earth experienced a global climate shift in the late 1980s on an unprecedented scale, fuelled by anthropogenic warming and a volcanic eruption, according to new research published this week.

Scientists say that a major step change, or ‘regime shift’, in the Earth’s biophysical systems, from the upper atmosphere to the depths of the ocean and from...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...

Im Focus: Laser process simulation available as app for first time

In laser material processing, the simulation of processes has made great strides over the past few years. Today, the software can predict relatively well what will happen on the workpiece. Unfortunately, it is also highly complex and requires a lot of computing time. Thanks to clever simplification, experts from Fraunhofer ILT are now able to offer the first-ever simulation software that calculates processes in real time and also runs on tablet computers and smartphones. The fast software enables users to do without expensive experiments and to find optimum process parameters even more effectively.

Before now, the reliable simulation of laser processes was a job for experts. Armed with sophisticated software packages and after many hours on computer...
