wacr > W-Band (95 GHz) ARM Cloud RadarInstrument Type(s) > Baseline

The W-band ARM Cloud Radar (WACR) systems are zenith-pointing Doppler radars that probe the extent and composition of clouds at 95.04 GHz.

The main purpose of this radar is to determine cloud boundaries (e.g., cloud bottoms and tops).

This radar reports estimates for the first three spectra moments for each range gate up to 15 km. The 0th moment is reflectivity, the 1st moment is radial velocity, and the 2nd moment is spectral width. Also available are the raw spectra files.

Unlike the millimeter wavelength cloud radar (MMCR), the WACR does not use pulse coding and operates in only copolarization and cross-polarization modes.
