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 are contingent upon adherence to standardized measurement protocols and rigorous uncertainty assessment methodologies. Reference measurements are the only traceable to the International System of Units (SI) and provided with a robust quantification of measurement uncertainty. This Short Course will guide the participants on improving knowledge and usage of reference measurements for climate studies and applications, by introducing three subtopics:
1. Reference upper air measurements
2. Near surface reference measurements
3. Precipitable water vapour from reference and reprocessed GNSS timeseries
Participants will be introduced to the theory, the contest and the potential applications in using reference measurements to characterize the atmosphere and investigate climate variability. Practical example of how to use reference measurements will be shown and discussed, also exploring the Copernicus Climate Data Store, currently hosting a few reference datasets.
