The Lead Centre will participate to the WMO TECO 2016 conference and the International Conference on Metrology for Meteorology and Climate with poster presentations on the more recent research developments and ongoing collaborations.

Wind tunnel experiments are currently under execution at the DICCA laboratories to provide information on rain gauges performance under turbulent winds and validation of CFD numerical analysis.

Oral presentation at the AMS annual meeting in New Orleans. Download the presentation.

Oral and poster presentations at the UrbanRain workshop (Pontresina). Download the short paper on the jointed CFD activity with EML.

The Lead Centre “Benedetto Castelli” on Precipitation Intensity was designated by the WMO/CIMO in September 2010 with the aim of providing specific guidance about instrument calibration and their achievable accuracy, performing laboratory and field tests and developing research/technical activities about the measurement of precipitation intensity and the related data analysis and interpretation.

The Lead Centre is a joint initiative of the Italian (Air Force) Meteorological Service and the University of Genova (Italy), and operates in three different sites: the Field Test site in Vigna di Valle (Rome – I), the Precipitation Laboratory at the University of Genova (Genoa – I), the Mountain site at the top of Mt. Cimone (Modena– I).

CIMO-XV agreed with the proposal to establish CIMO Testbeds and Lead Centres to promote collaboration between CIMO and relevant NMHSs in testing, development and standardization of meteorological instruments and systems performance for the benefit of all WMO Members. It would utilize and build on both existing state-of-the-art facilities and specific expertise available at NMHSs for the provision of guidance to all WMO Members, while providing recognition by CIMO of state-of-the-art facilities and expertise available in the designated Testbeds and Lead Centres, as well as of their significant contribution towards developing guidance for WMO Members, and their impact on the WMO observing systems.
