WindRose Studio
User Guide
WindRose Studio is a professional tool designed to support rigorous environmental and atmospheric analyses based on ERA5 reanalysis data.
The application guides the user through the correct preparation, inspection and quality assessment of meteorological datasets, with a specific focus on wind climatology, data completeness, temporal consistency and spatial coherence.
WindRose Studio interprets GRIB files, reconstructs their temporal and spatial structure, detects inconsistencies and missing information, and provides technically sound summaries that can be used with confidence in dispersion modelling, regulatory assessments and environmental studies.
Particular care has been devoted to transparency and reproducibility: every processing step is explicit, every assumption is traceable, and the user always retains full control over the source data and the analysis workflow.
Purpose of the ERA5 Wizard
The ERA5 Wizard supports environmental professionals in planning meteorological data requests from the Copernicus Climate Data Store (CDS) through a structured and methodologically transparent workflow.
The Copernicus portal provides access to global reanalysis data spanning several decades, covering virtually any location on Earth. It offers a rich set of configuration options: spatial domains, temporal ranges, pressure levels, single-level variables, product types and output formats.
For users who are primarily interested in obtaining a coherent meteorological dataset rather than navigating the full technical interface of the CDS, this abundance of options can become a source of uncertainty.
The Wizard was developed to provide orientation within this complexity. It guides the user in defining the essential parameters of an ERA5 dataset:
- the geographic reference location,
- the spatial subregion to be extracted,
- the temporal coverage of the request,
- the set of ERA5 variables appropriate for the intended analytical objective.
These elements determine the spatial extent, temporal completeness and physical meaning of the dataset that will be generated. Making these parameters explicit at the request stage ensures that the downloaded GRIB file reflects a deliberate methodological choice.
The dataset prepared through the Wizard can then be imported into WindRose Studio, where the internal GRIB structure is inspected and the spatial interpretation of the data is performed in the “Analyze GRIB” phase. The Wizard therefore establishes the foundation for a consistent and traceable analytical workflow.
