Ka ARM Zenith Radar (KAZR): filtered spectral data, moderate sensitivity mode, co-polarized mode - kazrspeccmaskmdcopol

The Ka-band ARM Zenith Radar (KAZR) remotely probes the extent and composition of clouds at millimeter wavelengths. The KAZR is a zenith-pointing Doppler radar that operates at a frequency of approximately 35 GHz. The main purpose of this radar is to determine the first three Doppler moments (reflectivity, vertical velocity, and spectral width) at a range resolution of approximately 30 meters from near-ground to nearly 20 km in altitude. \n \nThe KAZR replaces the millimeter-wavelength cloud radar (MMCR) and uses a new digital receiver that provides higher spatial and temporal resolution than the MMCR. In addition, spectral artifacts in the data are significantly reduced in the KAZR, allowing researchers to study cloud dynamics much more closely than with the MMCR.Ka波段ARM天顶雷达（Ka-band ARM Zenith Radar，KAZR）通过毫米波段对云的分布范围与组成成分开展遥感探测。该雷达为天顶指向型多普勒雷达，工作频率约为35吉赫兹（GHz）。本雷达的核心功能是获取前三级多普勒矩量（包括反射率、垂直速度与谱宽），探测距离分辨率约为30米，探测高度覆盖从近地面至近20千米的高空。 KAZR替代了原毫米波长云雷达（millimeter-wavelength cloud radar，MMCR），其搭载的新型数字接收机相较MMCR具备更优异的空间与时间分辨率。此外，KAZR采集的数据中频谱伪影显著减少，使得研究人员能够比使用MMCR时更细致地开展云动力学相关研究。
