摘要美国国家海洋和大气管理局高层大气物理实验室修改了一个标准的915 MHz剖面仪，用作降水剖面仪，以支持热带降雨测量使命地面验证现场活动。这款剖面仪经过改装，可以通过固定的碟形天线垂直观察。它在1998年4月至5月在德克萨斯州南部进行的德克萨斯州和佛罗里达州低空飞行实验（TEFLUN）A期间和1998年8月至9月在佛罗里达州中部进行的TEFLUN B期间进行了操作。与侧写器搭配的是Distromet公司，RD-69 Joss-Waldvogel转速计在得克萨斯州和佛罗里达和二维视频转速计在佛罗里达。这些测距仪用于在最低距离门处校准剖面仪。在更高的高度，校准的廓线反射率进行比较，由扫描雷达，如天气监视雷达-1988年多普勒在迪金森，得克萨斯州，墨尔本，佛罗里达，和S波段多普勒双极化雷达在佛罗里达。作者conc…
Abstract The National Oceanic and Atmospheric Administration’s Aeronomy Laboratory has modified a standard 915-MHz profiler for use as a precipitation profiler in support of Tropical Rainfall Measuring Mission ground validation field campaigns. This profiler was modified to look vertically with a fixed dish antenna. It was operated during the Texas and Florida Underflights Experiment (TEFLUN) A in south Texas in April–May 1998 and during TEFLUN B in central Florida in August–September 1998. Collocated with the profiler was a Distromet, Inc., RD-69 Joss–Waldvogel disdrometer in Texas and Florida and a two-dimensional video disdrometer in Florida. The disdrometers are used to calibrate the profiler at the lowest range gates. At higher altitudes, the calibrated profiler reflectivities are compared with observations made by scanning radars such as the Weather Surveillance Radar-1988 Doppler in Dickinson, Texas, and Melbourne, Florida, and the S-band Doppler dual-polarization radar in Florida.
