Help Advance Hail Research! Calling all chasers!

[V. Gensini]

Chasing community,

If you’re out chasing, you’re in a unique position to capture some of the most valuable hail observations available. We invite you to contribute your hail reports to the ICECHIP database and help improve our understanding of severe hail events. We’re especially interested in accurate measurements, not estimates. When possible, please report:

• Maximum dimension (Z) — the largest distance across the hailstone
• X and Y dimensions — measured perpendicular to each other
• Weight (grams) — optional but extremely valuable
• Photos and notes on storm context or damage

Even reports of no hail observed are useful for validation and improving spatial accuracy. E.g., when you are measuring across a hail swath, feel free to submit a report to note that no more hail is observed. Your contributions directly support research on hail size distributions, storm processes, and impacts—helping bridge the gap between field observations and forecasting.

Accurate data from the field makes a difference—thanks for your help!
