Berry CV

Position and Expertise

Dr. Edwin X Berry is a physicist, a Certified Consulting Meteorologist (CCM) by the American Meteorological Society (AMS), and CEO of Climate Physics, LLC. His expertise is in atmospheric physics, climate physics, numerical models, and the philosophy of science.


Berry received his BS in Engineering from the California Institute of Technology (Caltech) in 1957, where he studied under Linus Pauling and other excellent professors.

While at Caltech, Berry served in the Air Force ROTC as a pilot trainee. Near graduation the officers informed the pilot-trainees that Congress had reduced their budget for pilots. So, the AFROTC gave Berry an honorable discharge.

After graduating from Caltech, he worked as a physics instructor at Sacramento State University while he studied math and statistics.

In 1959, Dartmouth College awarded Berry a teaching fellowship in physics. In addition to physics, Berry studied probability and Markov chains, and the philosophy of science under John Kemeny, who studied under Albert Einstein. Berry’s master’s thesis, under Professor Millet Morgan, was about the polarization of high-frequency radio waves beamed into the earth’s ionosphere.

Berry received his MA in Physics from Dartmouth College in 1960.

In 1961, Berry became the first research assistant of the new Desert Research Institute at the University of Nevada, Reno. Berry’s PhD physics mentor was Friedwart Winterberg, the top student of Nobel Laureate Werner Heisenberg. William T. Scott also mentored Berry.

Berry received his PhD in Physics, with minors in atmospheric physics and math, from the University of Nevada in 1965.

Desert Research Institute, University of Nevada

Berry taught graduate physics courses in fluid dynamics while he continued his research.

Berry was chief scientist for Nevada’s Desert Research Institute airborne research facility. He planned and led pioneering research flights inside Alberta hailstorms and Sierra Nevada mountain storms.

Berry designed, and his team built, the first airborne, earth-referenced radar display for weather research, which predated modern GPS instruments. National Oceanographic and Atmospheric Agency (NOAA) adapted Berry’s design for hurricane research.

Consultant work

He participated as a consultant in federal-government-sponsored meteorological research experiments in the USA, Canada, South Africa, Puerto Rico, St. Croix, and the Philippine Islands.

Dr. Pierre St. Amand, of the Naval Weapons Center, invited Berry to be a regular consultant to the Department of Defense (DOD). In 1969, St. Amand invited Berry to be the only civilian consultant in DOD’s top-secret “Operation Popeye” weather modification project in the Philippines. Berry and St. Amand used C-130 aircraft to teach US Air Force (USAF) B-52 pilots how to produce rain by dynamically seeding tropical clouds.

National Science Foundation Program Manager

In 1972, the National Science Foundation (NSF) invited Berry to be its Program Manager for Weather Modification. Berry managed NSF’s leading edge-national weather research projects, including the Metropolitan Meteorological Experiment (METROMEX) and the National Hail Research Experiment (NHRE).

The Metropolitan Meteorological Experiment (METROMEX) was a major research project to quantify the inadvertent weather modification by a large city. Extensive measurements in and around St. Louis showed how the heat island effect of the city modified the surrounding weather and climate. The project budget was $5 million per year plus significant contributions from the US Air Force.

The National Hail Research Experiment (NHRE) was a major research project to study the microphysics and dynamics of large hail storms on the east slope of the Rocky Mountains. The project budget was $5 million per year.

As NSF Program Manager, Berry convened a special task force to study the statistical methods required to evaluate weather modification experiments. Statistical experts from the University of California, Berkeley, concluded that weather modification evaluation was the most difficult statistical problem they had encountered.


When in high school, Berry scored a perfect 800 on the quantitative SAT test while finishing an hour ahead before the allotted time. A few years later, he scored 100 percent on the Selective Service written test while finishing an hour before the allotted time.

Berry’s theoretical PhD thesis, “Cloud Droplet Growth by Collection,” is still cited as a breakthrough in the science of rain formation and in the use of numerical models. His work is summarized in cloud physics textbooks.

Berry is a pilot, with glider, power, and instrument ratings.

In 1976, Berry founded Edwin X Berry & Associates in Sacramento. Later, he founded Atmospheric Research & Technology and Amerivision Corporation.

He developed numerical models to calculate and reduce aircraft accidents caused by wind shear. He worked with United Airline pilots in simulators to test his ideas about wind shear on aircraft. He helped United Airlines to develop safe landing methods during wind-shear conditions. He proposed a method to detect wind shear over airports which the Federal Aviation Agency (FAA) installed at major airports.

He performed the southern California desert wind-energy study for the California Energy Commission. He was first to identify Altamont Pass and Tehachapi Pass as excellent wind energy resources.

He designed, and his team manufactured, the first low-cost, electronic remote data instruments for wind energy using then state-of-the-art electronics, and helped private companies evaluate wind-energy potential on their land.

From 1989 through 1992, Berry managed his meteorological team to provide 24-hour weather forecasting for the US Customs Aerostat project along the southern U.S. border.

In 1991, Berry developed software that used historical annual streamflow data to estimate future annual streamflow for the Sacramento River Index. His cycle-based software accurately predicted California would recover from its 1993 drought and that drought would reoccur in 2013.

Berry has been an expert witness in many legal trials and has never been on the losing side of a trial.

In 1992, Berry made courtroom history by developing and defending the first computer model to generate new evidence in a criminal trial. His custom software application, written in Microsoft Visual Basic, modeled human body physiological responses to changing weather and environmental conditions. This model and Berry’s testimony were key in the successful defense in a high-profile murder trial.

Computerworld and Microsoft selected Berry’s model as one of 24 finalists out of 1300 entries for the 1993 Windows World Open where it won the overall “People’s Choice Award.” Microsoft nominated Berry for a Smithsonian Award.

In 1996, the University of Nevada Alumni Association presented Berry with its Professional Achievement Award, after he was nominated by his physics mentor, Friedwart Winterberg.

From 1994 through 2000, Berry developed software that applied mathematical artificial intelligence methods, developed for weather forecasting, to the valuation of single-family homes. The Bank of America performed side-by-side tests of Berry’s model against other home valuation methods. Berry’s method proved significantly superior.

Climate research

In 2001, Berry began focusing on the global warming research, which is intimately tied to his expertise in cloud physics, numerical modeling, complex systems, and government-sponsored research. He has self-funded his climate research since 2001.

Berry moved to Bigfork, Montana, in 2008.

Berry led the successful Montana fight to stop the “Our Children’s Trust” climate lawsuit in the Montana Supreme Court. Berry’s testimony stopped several climate bills from passing in Montana’s legislature.

Berry manages his climate research and maintains close interaction with many other climate scientists via the Internet and professional meetings.

Berry began his self-funded website ( in 2009 to educate and inform the public about climate science. He is experienced in communicating with the general public and scientists. He has many subscribers to his climate website.


Berry’s main publications are listed on His professional publications continue to gather citations from new publications by other authors.

Athletic achievements

During his professional career, Berry has been very active in athletic competitions.

After graduating from Caltech, Berry spent the summer training under Ed Parker in his first “gang of 8” Kenpo Karate class in Altadena, California. The most valuable part of the training was how to fall. Parker’s training allowed Berry, years later, to endure two serious falls on his back onto concrete with absolutely no injury.

When a graduate student at University of Nevada, his athletic performance won him a membership in the elite Sigma Delta Psi national athletic honorary society. Others who have achieved this level of athletic performance include Astronaut Edward White, super-athlete Norm Hoffman, Dr. Fred Hatfield, and Dr. Thomas Cureton.

As a competitive small-boat sailor, Berry and his wife, Valerie, as crew, beat Olympic sailors and won Gold Medals in the 1974 Canadian Olympic Regatta in Kingston, Ontario (CORK). They also won North American and US National Championships.

In the 1990’s, Berry placed in the USA top 10 age-group run-bike-run events. In the 2000’s, he placed in the top 3 in international senior track competition for races 100, 200, 400, and 1500 meters.

Currently, Berry is active in Concept 2 indoor rowing competition. He holds world first places in 100, 500, and 1000 meters and one-minute row events for age-group 80-89, lightweight. Berry maintains second or third world places when competing with the heavyweights.
