Company's Scientific Team Reports First North American Field Evidence That Ground-Based Ionization Increases Wintertime Snowpack

NAPLES, FL / ACCESS Newswire / July 30, 2026 / Rain Enhancement Technologies Holdco, Inc. (NASDAQ:RAIN), a leading provider of ionization rain and snowfall enhancement technology, today announced that its scientific team will present four precipitation enhancement field studies at the AMS Madison Summit, a convening of six American Meteorological Society specialty conferences bringing together atmospheric scientists across weather forecasting, severe storms, cloud physics, mountain meteorology, and weather modification, August 3-7, 2026, in Madison, Wisconsin.

RET's presentations are part of the 25th Conference on Planned and Inadvertent Weather Modification. The presentations represent the first peer-reviewed scientific forum appearances for RET's Weather Enhancement Technology Array (WETA) operational results, including the first quantitative field evidence that ground-based ionization can enhance cold-season orographic precipitation in North American mountain ranges.

Senior Meteorologist Dr. Jeffrey Chagnon will present "First North American Field Evaluation of Ground-Based Ionization for Wintertime Precipitation Enhancement," reporting results from the first North American field deployment of ground-based ionization technology for wintertime snowpack enhancement. Despite historically dry conditions during the 2025-2026 winter, statistically significant enhancement of both snow depth and snow water equivalent was observed relative to expectations derived from control site behavior and historical analogs.

Data Scientist Rutuja Dongre will present "Enhancement Above Expectation: Rigorous Statistical Evaluation of Weather Modification Performance," outlining RET's multifaceted statistical framework for evaluating precipitation enhancement from ground-based atmospheric ionization systems, including difference-in-differences techniques, Bayesian Structural Time Series models, and ridge regression counterfactual modeling.

VP of Engineering Scott Morris will present "Chemical-Free Cloud Seeding: Operational Results from Ground-Based Ionization Systems in Utah," examining the operational deployment of the WETA at the La Sal Mountains in Utah beginning November 2025. The presentation details system specifications and integration with meteorological monitoring networks including SNOTEL sensors, WSR-88D radar, and radiometer observations.

Research Engineer Taylor Gresham will present "Electrostatic Fog Dispersal: Deployment and Optimization of Ground-Based Ionization System," detailing the deployment, instrumentation strategy, and optimization framework for field trials of RET's Fog Removal by Electrical Activity (FREA) system near the Myall River, New South Wales, Australia.

"Presenting four studies at the AMS Weather Modification Conference is a significant milestone for our scientific team and for the field of ionization-based precipitation enhancement," said Randy Seidl, Chief Executive Officer of Rain Enhancement Technologies. "The La Sal Mountains results represent the first quantitative field evidence of this kind in North America, and we look forward to sharing our methodology and findings with the broader weather modification community."

"The peer-reviewed scientific community is where this work belongs," said Dr. Jeffrey Chagnon, Senior Meteorologist at Rain Enhancement Technologies. "Our statistical framework was specifically designed to produce rigorous, uncertainty-quantified results that can withstand scientific scrutiny. Presenting at AMS is the natural next step in establishing ground-based ionization as a credible and replicable approach to precipitation enhancement."

RET's WETA platform uses a ground-based ionization process rather than traditional chemical-based cloud seeding, operates autonomously without aerial operations or chemical dispersal, and functions year-round rather than being limited to sub-freezing conditions. In its first full winter of operation at the La Sal Mountains in Utah, the WETA produced more than 20% Snow Water Equivalent enhancement - confirmed by three independent statistical methods and reviewed by Dr. Binod Pokharel of Utah State University - generating an estimated 8,750 acre-feet of incremental water at a validated cost of $10 per acre-foot.

The AMS Madison Summit will be held August 3-7, 2026, at the Monona Terrace Community and Convention Center in Madison, Wisconsin.
