Abstract
The study describes signi?cant outcomes of the 'Metrology for Meteorology' project, MeteoMet, which is anattempt to bridge the meteorological and metrological communities. The concept of traceability, an idea used in both ?eldsbut with a subtle difference in meaning, is at the heart of the project. For meteorology, a traceable measurement is the one thatcan be traced back to a particular instrument, time and location. From a metrological perspective, traceability further impliesthat the measurement can be traced back to a primary realization of the quantity being measured in terms of the base units ofthe International System of Units, the SI. These two perspectives re?ect long-standing differences in culture and practice andthis project - and this study - represents only the ?rst step towards better communication between the two communities.The 3 year MeteoMet project was funded by the European Metrology Research Program (EMRP) and involved 18 EuropeanNational Metrological Institutes, 3 universities and 35 collaborating stakeholders including national meteorology organiza-tions, research institutes, universities, associations and instrument companies.The project brought a metrological perspective to several long-standing measurement problems in meteorology and climatol-ogy, varying from conventional ground-based measurements to those made in the upper atmosphere. It included developmentand testing of novel instrumentation as well as improved calibration procedures and facilities, instrument intercomparisonunder realistic conditions and best practice dissemination.
