Researchers are probing hail’s formation and impacts at a specialized cold lab in Boulder, where scientists slice and analyze hailstone layers, crystals, particles and isotopes to reconstruct how stones grew inside storms. That lab work anchors ICECHIP, a major 2025 field campaign that deployed about 100 scientists across the Central Plains and Front Range with radar trucks, drones, high-speed cameras, disdrometers, foam pads, balloons and hail-like probes to measure hail on the ground and aloft. ICECHIP secured $11 million in NSF funding and delivered a comprehensive dataset intended to improve forecasts, warnings and engineering responses, but the future of the National Center for Atmospheric Research - home to the cold lab - is politically contested, prompting litigation to block a proposed dissolution that researchers say would seriously harm U.S. hail science.
The research frames hail as a multibillion-dollar problem: nationwide severe-thunderstorm losses exceeded $50 billion annually from 2023-2025, with hail causing 60-80 percent of the damage, and Colorado illustrates the trend as hail drives rising premiums and expensive repairs. Scientists show warming will shrink some stones before they land but strengthen updrafts that allow the largest, most destructive hailstones to grow, so damaging hail will become more common. Combined with rapid development in hail-prone corridors - the “expanding bull’s-eye effect” - this increases exposure, prompting new building codes, grant programs and material-testing efforts to reduce future losses.
