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 knowledge for his local weather fashions, that are used to forecast and observe flash floods.
Predicting floods is essential for rapidly evacuating residents in affected areas and defending properties and companies in opposition to injury.

Her colleague “stated researchers within the area had restricted measurements as a result of the gear meteorologists used to gather climate knowledge—together with radar satellites—is dear 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 velocity, and precipitation ranges is commonly inconsistent—which is an issue when making an attempt to supply correct fashions and predictions.
An knowledgeable in sign processing and mobile communication, Messer-Yaron got here up with the thought of utilizing current wi-fi communication alerts to gather climate knowledge, as communication networks are unfold throughout the globe.
In 2006 she and her analysis group developed algorithms that course of and analyze knowledge collected by communication networks to watch rainfall. They measure the distinction in amplitude of the alerts transmitted and obtained by the methods to extract knowledge wanted to foretell flash floods.
The strategy 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 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 will get inside the group, was actually a shock, and I used to be extraordinarily joyful to [receive] it,” she says. “I used to be proud that IEEE was capable of consider and see the potential in our expertise for public good and to reward it.”
A ardour for instructing
Rising up in Israel, Messer-Yaron was serious about artwork, literature, and science. When it got here time to decide on a profession, she discovered it tough to determine, she says. In the end, she selected electrical engineering, figuring it might be simpler to get pleasure from artwork and literature as hobbies.
After finishing her necessary 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 matter,” she says. “As an undergrad, you study all of the components 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 schooling there, incomes grasp’s and doctoral levels in 1979 and 1984. She moved to america for a postdoctoral place at Yale. There she labored with IEEE Life Fellow Peter Schultheiss, who was identified for his analysis in utilizing sensor array methods 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 change into 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 subsequent 14 years, she carried out analysis in statistical sign processing, time-delay estimation, and sensor array processing.
Her ardour for instructing took her around the globe 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 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 supplied a chance 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 subsequent three years oversaw the nation’s science coverage.
“I imagine [working in the public sector] is a part of our obligation as college 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 expertise.

Utilizing sign processing to watch climate
As a result of the planet is warming, the danger of flash floods is steadily growing. Hotter air holds extra water—which results in heavier-than-usual rainfall and ends in extra flooding, based on the U.S. Environmental Safety Company.
Information about rainfall is usually collected by satellite tv for pc radar and ground-based rain gauges. Nonetheless, radar photos don’t present researchers with exact readings of what’s taking place on the bottom, based on an Ensia article. Rain gauges are correct however present knowledge from small areas solely.
So Messer-Yaron set her sights on creating expertise 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 methods mechanically document 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 vital to trace rainfall utilizing the sign processing algorithms.
In 2005 Messer-Yaron and her group efficiently examined the expertise. The next yr, 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, nonetheless, that negotiating offers with mobile service firms in different international locations has been tough.
To increase the expertise’s use worldwide, Messer-Yaron launched a analysis community by means of the European Cooperation in Science and Expertise (COST), known as an opportunistic precipitation sensing community often called OPENSENSE. The group connects researchers, meteorologists, and different consultants around the globe to collaborate on integrating the expertise in members’ communities.
Since creating the expertise, Messer-Yaron has held plenty of jobs together with president of the Open College of Israel and vice chair of the nation’s Council for Increased Training, which accredits educational establishments.
She is sustaining her hyperlink with Tel Aviv College at present 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 creating expertise to watch 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 knowledge. Messer-Yaron served as its chief scientist till 2017.
She continues to replace the unique algorithms together with her college students, most just lately with machine studying capabilities to extract knowledge from bodily measurements of the sign degree in communication networks.
A worldwide engineering neighborhood
When Messer-Yaron was an undergraduate scholar, she joined IEEE on the suggestion of certainly 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 Sign Processing Society. From 1994 to 2010 she served on the society’s Sign Processing Concept 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.
Prior to now 10 years, she’s been concerned with different IEEE committees together with the conduct assessment, ethics and member conduct, and international public coverage our bodies.
“I don’t see my profession or my skilled life with out the IEEE,” she says
