915-MHz Radar Wind Profiler/RASS (RWP915): wind consensus data - 915rwpwindcon

\n \nThe radar wind profiler/radio acoustic sounding system (RWP/RASS), available in 915-MHz (for U.S. deployments) and 1290-MHz (for foreign deployments), measures wind profiles and backscattered signal strength between (nominally) 0.1 km and 5 km and virtual temperature profiles between 0.1 km and 2.5 km. However, ARM no longer operates the RASS portion. \n \nThe RWP transmits electromagnetic energy into the atmosphere in as many as five directions (four tilted in opposing vertical planes and on vertical) and measures the strength and frequency of backscattered energy. Calculation of the Doppler shift of the returned signal allows calculation of the atmospheric wind profile.雷达风廓线仪/无线电声学探测系统（RWP/RASS）可适配915-MHz（美国部署场景）与1290-MHz（海外部署场景）频段，可在标称0.1千米至5千米范围内获取风廓线与后向散射信号强度，并可在0.1千米至2.5千米范围内获取虚拟温度廓线。不过ARM已停止运行该系统的RASS模块。 该RWP最多可向五个方向向大气发射电磁能量，其中四个分别在对立垂直平面内倾斜，另一个沿垂直方向，并测量后向散射能量的强度与频率。通过对返回信号的多普勒频移进行计算，即可反演得到大气风廓线。
