Accurate and reliable observational data are fundamental for understanding climate dynamics, assessing climate change impacts, and informing adaptation strategies. However, the quality and consistency of observational datasets depend on adherence to standardized measurement protocols and rigorous uncertainty assessment methodologies. Reference measurements are the only traceable to the International System of Units (SI) and are provided with a robust quantification of measurement uncertainty.
This Short Course will guide participants in enhancing their knowledge and application of reference measurements for climate studies, with particular focus on the following topics:
1. Reference upper air measurements, Ruud Dirksen (DWD - Deutscher Wetterdienst)
2. Near surface reference measurements, Graziano Coppa (INRiM - Istituto Nazionale di Ricerca Metrologica)
3. Precipitable water vapour from reference and reprocessed GNSS timeseries, Olivier Bock (IPGP - Institut de physique du globe de Paris)
