This document is a report on metrology standards and practices at use in research infrastructures participating in ENVRIplus. It also identifies metrology needs, providing relevant concrete test cases where metrology developments are being made. First, a network of metrology contact point was established within the project (see Annex 1). This document is based on the expertise brought by this network. Section 1 identified the list of parameters common to at least 3 RIs to focus the gap analysis in terms of metrology needs on these parameters. Section 2 describes metrology practices on core parameters measured by the research infrastructures that can serve as a basis for exchange of good practices across ENVRIplus. The associated quality assessment and quality control procedures are also detailed. Each RI section ends with a short gap analysis in terms of metrological needs. Section 3 gives a panorama of the existing institutional metrology: BIPM at the global international level, EURAMET in Europe and new initiative in the frame of WMO called the GCOS Surface Reference Network (GSRN). The section ends with a general assessment of the traceability to standards in the RIs of ENVRIplus. Based on the gap analysis made in the project and funding opportunity, several concrete testcases, described in section 4, were initiated or further promoted, where metrology improvement relevant to ENVRIplus RIs are being developed via dedicated projects. Finally, section 5 describes the development of a metrology lab in the arctic, a fundamental observation area for climate change evaluation.
