Dynamic bias correction of commercial microwave links by remote rain gauges

Original language description

Efficient urban storm water management relies on rainfall information of high spatial and temporal resolution which is unfortunately often not available. Commercial microwave links (MWLs) represent an alternative source of rainfall information which could aid in this regard. MWLs are point-to-point radio systems widely used in telecommunication. They operate at frequencies where rainfall represents a significant source of signal attenuation. This attenuation is conceptually easily available online and can be related to rain rate. Although, MWLs reflect very well spatio-temporal structure of rainfall fallen on an urban catchment (as they are very dense in urban areas and operate close to the surface) their rain rate estimates are often biased. In this investigation we introduce a novel method to dynamically correct MWL bias using cumulative rainfall from remote rain gauges (RGs) with 1-hour temporal resolution, i.e. rainfall information usually provided by national weather services.
