The global spread of wireless networks brings a great opportunity for their use in environmental studies. Weather, atmospheric conditions, and constituents cause propagation impairments on radio links. As such, while providing communication facilities, existing wireless communication systems can be used as a widely distributed, high-resolution atmospheric observation network, operating in real time with minimum supervision and without additional cost. Here we demonstrate how measurements of the received signal level, which are made in a cellular network, provide reliable measurements for surface rainfall. We compare the estimated rainfall intensity with radar and rain gauge measurements.
无线网络的全球传播为其在环境研究中的应用带来了巨大机遇。天气、大气条件和成分会对无线电链路造成传播损伤。因此，在提供通信设施的同时，现有的无线通信系统可被用作一个广泛分布的、高分辨率的大气观测网络，以最少的监督实时运行且无需额外成本。在此，我们展示了在蜂窝网络中进行的接收信号电平测量如何为地面降雨提供可靠测量。我们将估计的降雨强度与雷达和雨量计测量结果进行比较。
