Checks Overview
cc_plugin-wcrp is built from many atomic checks, grouped by category. Eah plugin (e.g., wcrp_cmip6, wcrp_cordex_cmip6) just decides which ones to run; each category focuses on a specific aspect of file quality.
📏 Dimension Checks
Ensure that all dimensions exist and match the variable shapes.
These checks confirm that:
- Dimensions (e.g. time, lat, lon, bnds) are present.
- Their sizes are positive and coherent with variable shapes.
- Bounds variables (e.g. time_bnds) are consistent in size and order.
📊 Variable Checks
Ensure variables are present, their shape matches their dimensions, and (when bounds are declared) each value lies within its bounds.
⏱️ Time Checks
Focus on the time axis: presence of bounds with the right shape, and consistency between the time axis and the filename’s time range.
🏷️ Attribute Checks
Check that mandatory global and variable attributes are there, correctly typed/encoded, and their values are valid against regex patterns or controlled vocabularies.
📁 DRS & Path Consistency Checks
Validate filenames and directory paths and compare with the netcdf file's attributes; verify consistency between attributes like frequency vs table_id, experiment_id, institution, variant_label, etc., against project rules/CVs.
🧬 Data Plausibility Checks
Perform data-level plausibility tests on numeric variables:
- Check NaN and infinite .
- Check Constant .
- Check Fill Value or Missing values filling.
- Detect Physically impossible or statistically extreme outliers.
- Check Chunk size.
-
📦 File Format & Compression Checks
These checks ensure that the NetCDF file format and compression options comply with project and ESGF recommendations.
