Short summary
Hailstorms cause significant damage, yet measuring hail accurately remains difficult because current sensors have small sampling area and often confuse hail with rain. To solve this, we developed HailCam, a smart camera system, that counts and measures hail size every minute. Tests of the system prove that it is highly accurate and better than existing tools at ignoring rain. This technology is crucial to improve forecasts, warn communities earlier, and help scientists better understand storms.
