讨论了为平流层变化探测网络臭氧业务测量而开发的微波仪器。该仪器观察两个光谱线近3毫米波长的带宽为630兆赫，允许剖面检索从20至70公里。介绍了观测技术和定标过程。建立了测量正演模型和反演算法。初步比较共定位的地面激光雷达和SAGE II仪器。测量结果显示，通常在5%至10%范围内一致。
A microwave instrument developed for operational measurements of ozone for the Network for Detection of Stratospheric Change is discussed. The instrument observes two spectral lines near 3-mm wavelength with a bandwidth of 630 MHz, allowing profile retrieval from 20 to 70 km. The observing technique and calibration procedures are described. The measurement forward model and retrieval algorithm are formulated. Preliminary comparisons with a colocated ground-based lidar and the SAGE II instrument are presented. The measurements are shown to typically agree to within 5 to 10 percent.
