Dynamic bias correction of commercial microwave links

Popis výsledku v původním jazyce

Urban storm water management requires rainfall data of high spatial and temporal resolution which are often not available (Schilling, 1991). Path-integrated rain rate information from cellular microwave links (MWLs) has potential to aid in this regard (Messer et al., 2006) as MWL network are very dense in urban areas and rain rate information can be at virtually no cost polled from each single MWL with sub minute temporal resolution. Unfortunately MWL rainfall is often significantly biased (Fencl et al., 2015). In this investigation we proposed method to dynamically correct MWL rain rates by remote rain gauges (RGs) with hourly temporal resolution, i.e. RGs often operated by national weather services. Our results show that although these RGs have unsufficient resolution for most of the urban storm water management applications they can be conveniently used to calibrate MWL attenuation-rain rate model. Such calibrated model provides unbiased high-res quantitative precipitation estimates
