Like many innovators, Hagit Messer-Yaron had a life-changing concept whereas doing one thing mundane: Speaking with a colleague over a cup of espresso. The IEEE Life Fellow, who in 2006 was head of Tel Aviv University’s Porter School of Environmental Studies, was on the college’s cafeteria with a meteorological researcher. He shared his struggles with discovering high-resolution climate knowledge for his local weather fashions, that are used to forecast and monitor flash floods.
Predicting floods is essential for shortly evacuating residents in affected areas and defending houses and companies towards injury.

Her colleague “stated researchers within the area had restricted measurements as a result of the tools meteorologists used to gather climate knowledge—together with radar satellites—is pricey to buy and preserve, particularly in creating international locations,” Messer-Yaron says.
Due to that, she says, high-resolution knowledge about temperature, air high quality, wind pace, and precipitation ranges is commonly inconsistent—which is an issue when attempting to provide correct fashions and predictions.
An knowledgeable in sign processing and mobile communication, Messer-Yaron got here up with the concept of utilizing present wi-fi communication alerts to gather climate knowledge, as communication networks are unfold throughout the globe.
In 2006 she and her analysis crew developed algorithms that course of and analyze knowledge collected by communication networks to observe rainfall. They measure the distinction in amplitude of the alerts transmitted and obtained by the programs to extract knowledge wanted to foretell flash floods.
The tactic was first demonstrated in Israel. Messer-Yaron is working to combine it into communication networks worldwide.
For her work, she obtained this yr’s IEEE Medal for Environmental and Safety Technologies for “contributions to sensing of the setting utilizing wi-fi communication networks.” The award is sponsored by Toyota.
“Receiving an IEEE medal, which is the highest-level award you may get inside the group, was actually a shock, and I used to be extraordinarily completely satisfied to [receive] it,” she says. “I used to be proud that IEEE was in a position to consider and see the potential in our know-how for public good and to reward it.”
A ardour for educating
Rising up in Israel, Messer-Yaron was thinking about artwork, literature, and science. When it got here time to decide on a profession, she discovered it troublesome to determine, she says. In the end, she selected electrical engineering, figuring it could be simpler to get pleasure from artwork and literature as hobbies.
After finishing her necessary service within the Israel Defense Forces in 1973, she started her undergraduate research at Tel Aviv College, the place she discovered her ardour: Sign processing.
“Electrical engineering is a really broad subject,” she says. “As an undergrad, you be taught all of the elements that make up electrical engineering, together with utilized physics and utilized arithmetic. I actually loved utilized arithmetic and shortly found sign processing. I discovered it fairly superb how, through the use of algorithms, you possibly can direct alerts to extract data.”
She graduated with a bachelor’s diploma in EE in 1977 and continued her training there, incomes grasp’s and doctoral levels in 1979 and 1984. She moved to the US for a postdoctoral place at Yale. There she labored with IEEE Life Fellow Peter Schultheiss, who was recognized for his analysis in utilizing sensor array programs in underwater acoustics.
Impressed by Schultheiss’s ardour for educating, Messer-Yaron determined to pursue a profession in academia. She was employed by Tel Aviv College as {an electrical} engineering professor in 1986. She was the primary girl in Israel to turn into a full professor within the topic.
“Being a college member at a public college is the perfect job you are able to do. I didn’t make some huge cash, however on the finish of every day, I appeared again at what I did [with pride].”
For the following 14 years, she carried out analysis in statistical sign processing, time-delay estimation, and sensor array processing.
Her ardour for educating took her around the globe as a visiting professor at Yale, the New Jersey Institute of Technology, the Institut Polytechnique de Paris, and different faculties. She collaborated with colleagues from the colleges on analysis initiatives.
In 1999 she was promoted to director of Tel Aviv College’s undergraduate electrical engineering program.
A yr later, she was provided a chance she couldn’t refuse: Serving as chief scientist for the Israeli Ministry of Science, Culture, and Sports. She took a sabbatical from educating and for the following three years oversaw the nation’s science coverage.
“I imagine [working in the public sector] is a part of our responsibility as school members, particularly in public universities, as a result of that makes you a public mental,” she says. “Working for the federal government gave me a broad view of many issues that you simply don’t see as a professor, even in a big college.”
When she returned to the college in 2004, Messer-Yaron was appointed because the director of the brand new college of environmental research. She oversaw the allocation of analysis funding and spoke with researchers individually to higher perceive their wants. After having espresso with one researcher, she realized there was a have to develop higher weather-monitoring know-how.

Utilizing sign processing to observe climate
As a result of the planet is warming, the chance of flash floods is steadily growing. Hotter air holds extra water—which ends up in heavier-than-usual rainfall and leads to extra flooding, in accordance with the U.S. Environmental Protection Agency.
Knowledge about rainfall is often collected by satellite tv for pc radar and ground-based rain gauges. Nevertheless, radar pictures don’t present researchers with exact readings of what’s taking place on the bottom, in accordance with an Ensia article. Rain gauges are correct however present knowledge from small areas solely.
So Messer-Yaron set her sights on creating know-how that connects to mobile networks near the bottom to offer extra correct measurements, she says. Utilizing present infrastructure eliminates the necessity to construct new climate radars and climate stations.
Communication programs routinely report the transmitted sign degree and the obtained sign degree, however rain can alter in any other case easy wave patterns. By measuring the distinction within the amplitude, meteorologists might extract the info needed to trace rainfall utilizing the sign processing algorithms.
In 2005 Messer-Yaron and her group efficiently examined the know-how. The next yr, their “Environmental Monitoring by Wireless Communication Networks” paper was revealed in Science.
The algorithm is being utilized in Israel in partnership with all three of the nation’s main mobile service suppliers. Messer-Yaron acknowledges, nevertheless, that negotiating offers with mobile service firms in different international locations has been troublesome.
To develop the know-how’s use worldwide, Messer-Yaron launched a analysis community by way of the European Cooperation in Science and Technology (COST), referred to as an opportunistic precipitation sensing network generally known as OPENSENSE. The group connects researchers, meteorologists, and different specialists around the globe to collaborate on integrating the know-how in members’ communities.
Since creating the know-how, Messer-Yaron has held quite a few jobs together with president of the Open University of Israel and vice chair of the nation’s Council for Higher Education, which accredits tutorial establishments.
She is sustaining her hyperlink with Tel Aviv College at this time as a professor emerita.
“Being a college member at a public college is the perfect job you are able to do,” she says. “I didn’t make some huge cash, however on the finish of every day, I appeared again at what I did [with pride]. Due to the tutorial freedom and the autonomy I had, I used to be in a position to do many issues along with educating, together with analysis.”
To proceed her work in creating know-how to observe climate occasions, in 2016, she helped discovered ClimaCell, now Tomorrow.io, primarily based in Boston. The startup goals to make use of wi-fi communication infrastructure and IoT gadgets to gather real-time climate knowledge. Messer-Yaron served as its chief scientist till 2017.
She continues to replace the unique algorithms together with her college students, most not too long ago with machine learning capabilities to extract knowledge from bodily measurements of the sign degree in communication networks.
A world engineering neighborhood
When Messer-Yaron was an undergraduate scholar, she joined IEEE on the suggestion of considered one of her professors.
“I didn’t suppose a lot about the advantages of being a member till I turned a graduate scholar,” she says. “I began attending conferences and publishing papers in IEEE journals, and the group turned my skilled neighborhood.”
She is an energetic volunteer and a member of the IEEE Signal Processing Society. From 1994 to 2010 she served on the society’s Signal Processing Theory and Methods technical committee. She was affiliate editor of IEEE Signal Processing Letters and IEEE Transactions on Signal Processing. She is a member of the editorial boards of the IEEE Journal of Selected Topics in Signal Processing and IEEE Transactions on Sign Processing.
Prior to now 10 years, she’s been concerned with different IEEE committees together with the conduct review, ethics and member conduct, and global public policy our bodies.
“I don’t see my profession or my skilled life with out the IEEE,” she says
