Remedy 1: Improved characterisation of high quality instrumentation to increase the pool of reference quality observing techniques without necessitating new observational deployments

Primary gap remedy type: 
Proposed remedy description: 

Work to substantially improve the breadth of existing measurement techniques and programs that can be considered truly reference quality measurement systems. Building upon foundational work in existing EU H2020 projects such as QA4ECV, GAIA-CLIM, and FIDUCEO and by other international activities such as METEOMET, GRUAN, NDACC, GAW, the ESA Fiducial Reference Measurements program, etc. Undertake to improve the metrological characterisation of present and planned non-satellite measurement techniques for a broad range of atmospheric, oceanic, and terrestrial ECVs. Necessary steps include:

  • Full characterisation of the processing chain for each individual measurement technique considered;

  • Establishing traceability to SI or community standards;

  • Quantifying the uncertainty in each processing step with metrological rigor;
  • Ensuring comparability through necessary standardisation of techniques;

  • Documentation of final product via the peer-reviewed literature and associated documentation.

This work shall require the involvement of instrument experts, metrologists, and potential end-users. The remedy should involve those measurement networks, which may deploy the developed measurement techniques as key partners to ensure uptake of the newly developed measurement streams in the field. 


Directly addresses the paucity of reference-quality instrumentation by developing improved metrological understanding for a broad range of instrumentation that is either currently in the field or could be deployed. 

Measurable outcome of success: 

Improved number of reference qualified measurement techniques and increase in number of data streams available to end-users as a result. 

Expected viability for the outcome of success: 
  • Medium
  • High
Scale of work: 
  • Single institution
  • Consortium
Time bound to remedy: 
  • Less than 3 years
Indicative cost estimate (investment):
