New publication:
Cauteruccio et al. (2020)
The role of free-stream turbulence in attenuating the wind updraft above the collector of precipitation gauges.
Journal of Atmospheric and Oceanic Thechnology, 37, pages 103-113.

The first european standard on the accuracy of precipitation measurements instruments has been published as EN 17277:2019 "Hydrometry. Measurement requirements and classification of rainfall intensity measuring instruments"

kick-off meeting of the new EURAMET/EMPIR project INCIPIT "calibration and accuracy of non-catching instruments to measure liquid/solid atmospheric precipitation" hosted by the Lead Centre in Vigna di Valle.

The Lead Centre partecipated to the EGU general assembly 2019 in Vienna

The Lead Centre partecipated to the Meteorological Technology World Expo 2017 in Amsterdam

The Lead Centre partecipated to the Metoemet final meeting in Moncalieri (Tourin), presentig the results performed in the Research Excellence Grant (REG3) of the Meteomet2 project.

The Lead Centre partecipated to the EGU 2017 conference with poster presentations on wind tunnel experiments and precipitation measurements issues.

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.

General Terms of Reference for CIMO Lead Centres
  1. The purpose of CIMO Lead Centres is to provide high-level expertise in testing of instrument’s performance including in laboratory facilities, instrument intercomparisons and resulting in standardization of instruments’ performance, instrument interoperability and compatibility within WIGOS.
  2. CIMO Lead Centres will provide reports on all significant tests to the CIMO community, and in support of services of WIGOS and GFCS, through publication of IOM reports and publications in scientific journals, as appropriate.
  3. CIMO Lead Centres will be established by CIMO based on proposals from Members, on the basis that CIMO is confident that through the proposal and any supplementary information the proposed lead centre has the necessary capability, capacity and expertise and have made a long-term commitment.
  4. CIMO Lead Centres will contribute to the development of standard procedures for all aspects of instrument use and operation with a view to promote worldwide instrument compatibility and interoperability. They should provide advice related to instrument use, operation, calibration. CIMO Lead Centres will be expected to collaborate with relevant CIMO Expert Teams in developing guidance material and with RICs and RRCs, as relevant.
  5. CIMO Lead Centres should be instrumental in CIMO efforts to bridge gaps between countries by assisting CIMO in conducting training and capacity building activities.
  6. CIMO Lead Centre will provide at least one report every two years to CIMO-MG, publish IOM reports and where relevant provide contributions to TECOs. CIMO Lead Centres activity will be evaluated by CIMO-MG prior to each CIMO session to ensure they are delivering the expected outcomes.
  7. CIMO Lead Centres will liaise with CIMO via a CIMO Expert Team specified by CIMO-MG. CIMO Lead Centres must provide a Contact Person responsible for communication between the Lead Centre and CIMO.
  8. CIMO Lead Centres are requested to inform WMO if they do not have the capabilities to provide the expected service anymore, for example for human resource reasons.
