From my most recent trip to SGP. OK will always hold a special place in my heart. Some of the first meteorological instruments I ever worked with were at the Marvin Klemme Range Research station near Clinton. When I visit SGP I am reminded of where I started & the path I took to get where I am now.
A gravel road leads to a collection of meteorological research instruments mounted on several small buildings and observation decks. Several radar, and lidar systems are visible.

Proud of this one. The entire team worked so hard to get this site up and running. I'm so glad I get to work with the operations team there every day. Come visit us and bring your best science to the forest!

Things are getting interesting at our site in Alabama! My guess is this won't be a very common sight in the #BNF data, but time will tell. Anyone there remember that ice storm last winter?

Sometimes you just happen to be in the right place at the right time.
