I am an array of mobile/deployable weather radars (DOWs/COWs), weather stations, disdrometers, mesonets, & soundings. I look best in Carbone42.

I am the prettiest thing in this picture 😁
DOW A’s view of the tornado near Saint Libory, NE at 2 different times Image 1: 2211 UTC with eye Image 2: 2213 UTC with debris ball
Follow along… data eventually are geolocated 😬 svr.guru/data.php?id=...

17 years ago today! As part of VORTEX2, we parked in front of an incipient tornado and collected coordinated data (also I still thought radomes were cool 😎). Lots of papers were written about the Goshen tornado using DOW data! Learn more by going to our retro cool website 💾👇
Swirls, whirls, and windshield cracking hail 😬. All in a days work near Seibert, CO on 5/21/2026! Some of those swirls and whirls crossed our delta-V = 40m/s, “it’s a tornado”, threshold 🌪️ @nsficechip.bsky.social
Read all about it 📣📰! Latest updates on DOW tornado damage and evolution research. DOWs prepping to go out when atmosphere remembers that it is tornado season 🌪️

Under the mini COW 🐮 and Dow radar umbrellas 📡☂️, the heavy lifting was being done by the Pod People 👾! Pods were deployed near Coby, KS collecting the all-important thermodynamic and surface wind data in these hail storms 🧊! @nsficechip.bsky.social
Josh Wurman showing off the latest and greatest DOWA 😁 to the @climasillinois.bsky.social students and @kakosiba.bsky.social showing tornado 🌪️ data from the 2026 season 🤩! As always, a great group of students…and always happy to talk all things DOW 😁!

The storm-chasing @dowfacility.bsky.social research team got close observations of the devastating Greenfield, IA, tornado and powerful Duke, OK tornado in 2024. Those observations reveal new insights on how tornadoes evolve--and how they do damage. Read more: https://bit.ly/4uF6GG6
