These platforms, Super Mobile Hail Observatories (SuMHOs), will be deployed by members of the NHP field team across the US plains during the #ICECHIP field campaign. ICECHIP endeavours to improve radar-based #hail detection, hail models and forecasting, and hail warnings. @nsficechip.bsky.social

The NHP has been busy preparing for field operations, both at home and abroad! For the #ICECHIP field campaign, the NHP and Western's UMS designed and built 4 platforms which collect and preserve hailstones, capture high-speed video of falling #hail, and measure hail fall speed with a small radar.
