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.

Integrating Computational Fluid Dynamics (CFD) analysis into the KTP experimental design

Environmental Measurements Ltd (EML) is currently involved in a Knowledge Transfer Partnership with the School of Civil Engineering & Geosciences, Newcastle University, for a three-year project aiming to develop an innovative hydro-meteorological instrument for measuring rainfall accurately given any wind condition solving a fundamental problem in environment, water and climate change industries. Mr. Michael Pollock is a Research Associate working at this project at EML.




Environmental Measurements Ltd. (EML) wishes to achieve a sound quantitative assessment of the performance of its aerodynamic rain gauges, the ARG100 and the SBS range. CFD has the potential to provide a mathematically robust method of viewing the effect of the wind on a precipitation gauge, and thus provide a level of understanding which would allow the project team to improve the development of a correction algorithm.
Environmental Measurements Ltd. (EML) has identified the LC-PrIn as a potential contractor to carry out such a study. Both Parties thus exchanged information in order to evaluate the feasibility of such a study. It was agreed that a complementary research can be carried out and the conditions required to performing a study were defined.
