Like many innovators, Hagit Messer-Yaron had a life-changing thought 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 College’s Porter College of Environmental Research, was on the college’s cafeteria with a meteorological researcher. He shared his struggles with discovering high-resolution climate information 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 in opposition to injury.

Her colleague “mentioned researchers within the discipline had restricted measurements as a result of the gear meteorologists used to gather climate information—together with radar satellites—is pricey to buy and keep, particularly in growing international locations,” Messer-Yaron says.
Due to that, she says, high-resolution information about temperature, air high quality, wind velocity, and precipitation ranges is commonly inconsistent—which is an issue when making an attempt to provide correct fashions and predictions.
An knowledgeable in sign processing and mobile communication, Messer-Yaron got here up with the concept of utilizing current wi-fi communication alerts to gather climate information, as communication networks are unfold throughout the globe.
In 2006 she and her analysis group developed algorithms that course of and analyze information collected by communication networks to observe rainfall. They measure the distinction in amplitude of the alerts transmitted and obtained by the techniques to extract information 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 12 months’s IEEE Medal for Environmental and Security Applied sciences 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 glad to [receive] it,” she says. “I used to be proud that IEEE was capable of consider and see the potential in our know-how for public good and to reward it.”
A ardour for instructing
Rising up in Israel, Messer-Yaron was eager about artwork, literature, and science. When it got here time to decide on a profession, she discovered it troublesome to resolve, 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 obligatory service within the Israel Protection 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 study 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 may 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 USA 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 techniques in underwater acoustics.
Impressed by Schultheiss’s ardour for instructing, 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 grow to be a full professor within the topic.
“Being a college member at a public college is the most effective job you are able to do. I didn’t make some huge cash, however on the finish of every day, I regarded 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 instructing took her world wide as a visiting professor at Yale, the New Jersey Institute of Expertise, the Institut Polytechnique de Paris, and different colleges. She collaborated with colleagues from the schools on analysis initiatives.
In 1999 she was promoted to director of Tel Aviv College’s undergraduate electrical engineering program.
A 12 months later, she was supplied a possibility she couldn’t refuse: Serving as chief scientist for the Israeli Ministry of Science, Tradition, and Sports activities. She took a sabbatical from instructing and for the following three years oversaw the nation’s science coverage.
“I imagine [working in the public sector] is a part of our obligation 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 raised perceive their wants. After having espresso with one researcher, she realized there was a must 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 keeping with the U.S. Environmental Safety Company.
Information about rainfall is often collected by satellite tv for pc radar and ground-based rain gauges. Nonetheless, radar photographs don’t present researchers with exact readings of what’s taking place on the bottom, in keeping with an Ensia article. Rain gauges are correct however present information from small areas solely.
So Messer-Yaron set her sights on growing know-how that connects to mobile networks near the bottom to supply extra correct measurements, she says. Utilizing current infrastructure eliminates the necessity to construct new climate radars and climate stations.
Communication techniques routinely document the transmitted sign stage and the obtained sign stage, however rain can alter in any other case easy wave patterns. By measuring the distinction within the amplitude, meteorologists may extract the information crucial to trace rainfall utilizing the sign processing algorithms.
In 2005 Messer-Yaron and her group efficiently examined the know-how. The next 12 months, their “Environmental Monitoring by Wi-fi Communication Networks” paper was printed 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 Expertise (COST), known as an opportunistic precipitation sensing community often known as OPENSENSE. The group connects researchers, meteorologists, and different specialists world wide to collaborate on integrating the know-how in members’ communities.
Since growing the know-how, Messer-Yaron has held quite a lot of jobs together with president of the Open College of Israel and vice chair of the nation’s Council for Increased Schooling, which accredits educational 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 most effective job you are able to do,” she says. “I didn’t make some huge cash, however on the finish of every day, I regarded again at what I did [with pride]. Due to the educational freedom and the autonomy I had, I used to be capable of do many issues along with instructing, together with analysis.”
To proceed her work in growing know-how to observe climate occasions, in 2016, she helped discovered ClimaCell, now Tomorrow.io, based mostly in Boston. The startup goals to make use of wi-fi communication infrastructure and IoT units to gather real-time climate information. Messer-Yaron served as its chief scientist till 2017.
She continues to replace the unique algorithms along with her college students, most not too long ago with machine studying capabilities to extract information from bodily measurements of the sign stage in communication networks.
A world engineering neighborhood
When Messer-Yaron was an undergraduate pupil, she joined IEEE on the suggestion of one in every of her professors.
“I didn’t suppose a lot about the advantages of being a member till I turned a graduate pupil,” 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 Sign Processing Society. From 1994 to 2010 she served on the society’s Sign Processing Idea and Strategies technical committee. She was affiliate editor of IEEE Sign Processing Letters and IEEE Transactions on Sign Processing. She is a member of the editorial boards of the IEEE Journal of Chosen Subjects in Sign Processing and IEEE Transactions on Sign Processing.
Up to now 10 years, she’s been concerned with different IEEE committees together with the conduct assessment, ethics and member conduct, and world public coverage our bodies.
“I don’t see my profession or my skilled life with out the IEEE,” she says
