The Italian research team has conducted important theoretical and experimental studies about Radar meteorology, all of them published in prestigious international scientific journals. The studies have led to the affirmation of the dual-polarization technology as a reference standard for weather radar and the related methods for quantitative estimation of precipitation and cloud properties as well.
The technology developed and offered is based on the dual polarization C-band weather radar measurements collected by this radar in spherical coordinates, namely reflectivity factor, differential reflectivity, differential phase shift and mean Doppler velocity. Specific retrieval techniques are applied to obtain routinely geophysical products based on georeferenced grids. Products can be accessed by the authorized users through a web interface. Main products are:
a) Precipitation intensity (mm/h) at ground estimated according to a grid of 1x1 km resolution every 5-15 minutes. Higher spatial resolutions are possible for distance closer to the radar.
b) Precipitation accumulation computed with different accumulation time (15 minutes to 1 day or more)
c) Identification of hail bearing cells, and related hail probability
d) Very short term forecasting (nowcasting) through tracking of intense precipitation and hail bearing cores.
In agriculture, like in many other applications, the main source of data are the sparse raingauge networks: rainfall measurements from a single instrument of the network are collected at a network hub where, through interpolation techniques, precipitation data are provided onto the points of a given grid. Although reliable in the vicinity of a raingauge, uncertainty of rainfall estimates decreases as the distance from a raingauge increases. Instead, weather radar provides seamless products with a space resolution better than that achievable by standard dense raingauge networks, thus providing a more accurate spatial distribution of precipitation, allowing a precise estimation of places where precipitation is occurring Accurate identification and localization of hail are possible with dual polarization radar but not with raingauge.
The cooperation type desired is a technical cooperation agreement. The researchers are searching new partners to involve in designing, customizing and testing of products through cost sharing.
