The Collaborative Lower Mobile Atmospheric Profiling System (CLAMPS) is a trailer-based observing platform which integrates a Doppler lidar, microwave radiometer, and an atmospheric emitted radiance interferometer–or AERI–into one system. Two CLAMPS are housed at the NWC; CLAMPS1 is owned and operated by the Univeristy of Oklahoma while CLAMPS2 is owned and operated by NOAA-NSSL. Though they have different ownership, the C stands for collaborative, and the systems are operated as ‘sibling-systems’ priortizing coordination as much as possible. More information about CLAMPS and access to real-time and archived data can be found at the NSSL CLAMPS webpage.
