The calibration of instruments and the traceability of meteorological measurements to the International Standard (SI) of units are crucial to ensure the quality of meteorological observations and to meet the users’ requirements. Regional Instrument Centres (RICs) play a key role in this context, by providing calibration services to other Members of their Region. In view of the need to ensure the quality of the services provided by the RICs, and the need for strengthening of RICs, the WMO Executive Council requested CIMO to develop a mechanism for their continuous evaluation to ensure quality of their services and to verify the traceability of the basic meteorological variables. This publication describes the first Evaluation Scheme developed for Regional Instrument Centre’s regular assessment. It was developed by a member of the CIMO Expert Team on Regional Instrument Centre, Mr Jérôme Duvernoy. This report explains how to use the Evaluation Scheme for Regional Instrument Centres and Other Calibration Laboratories that consists in an Excel Sheet. It describes briefly the background of the Evaluation Scheme, the user manual and provides some guidance on the ISO 17025 standard “General requirements for the competence of testing and calibration laboratories”. The Evaluation Scheme itself is based on the Terms of Reference of RICs and on the ISO 17025 standard on which they rely. The Evaluation Scheme has been prepared in a way to help users in maintaining or strengthening their quality management system. It contains three main parts in the form of a questionnaire, results and improvement advices. This IOM Report can be considered as a tool that is useful for the regular assessment of RICs, but also as a help to establish the quality system of a RIC or of a calibration laboratory. The main benefits of correctly implementing ISO/IEC 17025 in a RIC or a NMHSs’ calibration laboratory are the continuous improvement of calibration quality and laboratory effectiveness, which also improve the data quality of observing parameters exchanged within WIGOS, as well as the improved national and regional recognition of the laboratory.
