PeronaPolitecnico di Torino, Dipartimento di Elettronica, Remote Sensing Group, Torino, Italy (stefano.turso@polito.it, +39 011 5644200)MicroRadarNet (MRN) is a network of high-resolution, low-cost, low-power consumption micro radars forcontinuous, unattended meteorological monitoring. The MRN project started in the framework of the EuropeanINTERREG IIIB Alpine Space Programme (within the FORALPS project) since 2004 and was developed andoperated by the Remote Sensing Group at the Politecnico di Torino from its early design stages. MRN is currentlyunder its release and operational validation phase, cooperating with professional weather operators (e.g. civilprotection offices) to run extensive on-field tests.The key aspects of MRN are a short range strategy (about thirty kilometers) and the implementation of an effectivesensor network approach. Raw spatial and temporal data is processed on-board in real-time, yielding a consistentevaluation of the information from the sensor and compressing the data to be transmitted. Network servers receiveand merge the data sets coming from each unit yielding a synthetic, high-resolution plot of meteorological events(updated every minute). This networked approach implies in turn a sensible reduction of the overall operationalcosts, including management and maintenance aspects, if compared to the traditional long range C-band approach.An ever-growing database of meteorological events is being collected, thus providing a real-data test bench torefine assessment and data enhancement algorithms. Assessment techniques have been adopted for the estimationof precipitation, based on systematic rain gauges comparisons. Efforts were also devoted to the design and imple-mentation of specific decluttering algorithms. New techniques to mitigate the effect of co-channel interferencesources are also under testing. It is shown how these enhancement algorithms further improve the assessmentprocess raising the overall data quality. Furthermore, new data analysis modules for the identification of precip-itation patterns are being evaluating, including tracking routines for the short term prediction of meteorologicalcells motion and morphing. We strongly expect that these enhancements will be of some interest to the final users,contributing to the relevance of the provided weather information. Finally, particular attention has been devoted toset up efficient data availability and presentation mechanisms in other to ease weather services access for a broadrange of purposes. Up-to-date Web techniques have been implemented accordingly.A consistent amount of case studies clearly shows that MicroRadarNet has enough potentialities to act as afast-reacting weather monitoring tool. The proposed strategy, based on a network of short range radars, shalleffectively collect high-resolution quality datasets while lowering the overall operational costs. This could prevent,by design, the volumetric resolution loss at higher ranges, as well as the need for atmospheric corrections and theshielding shortcomings which typically occur in orographically complex areas.
