Environment Canada Automated Mobile Meteorological Observing System (AMMOS) installed on Jeep for VORTEX2 – May 2009. AMMOS was used to sample mesoscale boundaries of interest before storm initiation, and coordinated with the other 6 mobile mesonets to run transects through storms.

May 13 storms in N Oklahoma. When we first found this hailstone, it was 60 mm in diameter (a baseball is 70 mm) and had really nice spikes. We got around to getting a photo about a half hour later, so it melted a bit. Still impressive! Credit: David Sills 2009
