摘要: The W-band Atmospheric Radiation Measurement (ARM) Program Cloud Radar (WACR) systems are zenith pointing Doppler radars that probe the extent and composition of clouds at 95.04 GHz. main purpose this radar is to determine cloud boundaries (e.g., bottoms tops). This reports estimates for first three spectra moments each range gate up 15 km. 0th moment reflectivity, 1st radial velocity, 2nd spectral width. Also available raw files. Unlike millimeter wavelength (MMCR), WACR does not use pulse coding operates in only copolarization cross-polarization modes.
