Electromagnetic waves are known to be influenced by atmospheric conditions. Therefore, wireless communications, in which electromagnetic signals carry the information, can be used in environmental studies. In a recently published paper, it has been demonstrated that received signal level (RSL) measurements from fixed terrestrial line-of-sight microwave links, deployed by cellular operators, can be used to estimate space-time rainfall intensities . In this follow-up paper we present recent real data results based on a rigorous algorithm which converts received signal level measurements from a set microwave links in an arbitrary geometry, lengths and frequencies into a two dimensional rain map. As such, the great potential of using globally spread wireless communication systems for accurate two dimensional rainfall monitoring has is exploited.
