The Scanning ARM Cloud Radar (SACR) is a ground-based Doppler radar system operated by the Department of Energy (DoE) Atmospheric Radiation Measurement (ARM) User Facility. It is a polarimetric Doppler radar comprising three radar designs operating at different frequencies: X-SACR (9.71 GHz), Ka-SACR (35.3 GHz), and W-SACR (94 GHz). At each deployment site, two SACR radars are deployed, with operating frequencies determined by atmospheric attenuation at the site. SACR provides measurements of radar reflectivity, Doppler velocity, spectrum width, and other polarimetric parameters at a gate spacing of 25 meters.
