EURAMET JRP ENV58 MeteoMet2 Research Excellence Grant #3

Starting from the experience achieved during the previous JRP ENV07 MeteoMet on the traceability to SI of some Essential Climate Variables (ECVs) and the evaluation of calibration uncertainties, JRP ENV58 MeteoMet2 aims to extend the investigations to other variables and at evaluating further aspects and contributions to the uncertainty. The aim is to make a further step towards the final goal: the evaluation of the overall measurements uncertainties for the quantities involved in the meteorological observations and climate change evaluations. The improvement of quality of ECVs recorded data through the inclusion of measurement uncertainty budget will bring to possible strategies for the reduction of the uncertainty. This JRP, which aims to develop metrological traceability for the measurement of main ECVs defined by GCOS1 , is structured in 3 work packages each covering a different area of observation: Air, Sea and Land. The ECVs considered are: water vapour in upper-air and surface atmosphere, surface and deep sea temperature, salinity, air temperature, precipitation, albedo, permafrost temperature and soil moisture.

The LC-PrIn will contribute to the definition of a fully traceable calibration procedure for catching and non-catching type precipitation gauges. In addition, the laboratory testing and the CFD activity will foster the development of correction algorithms for precipitation measurements obtained from catching-type precipitation gauges. Suggestions for the improvement of existing standards about precipitation intensity measurements (e.g. CEN TC318, UNI 11452:2012 and BS 7843–3:2011) will be provided.
