PHASE: Interpolated phenological phase entry dates for winter wheat (Triticum aestivum, DWD Plant ID 202) in Germany

Interpolated phenological phase entry dates (day-of-year) with a per-pixel uncertainty layer, from the PhenoPhaseR pipeline for winter wheat (Triticum aestivum L., DWD Plant ID 202), for Germany over 1993–2025 at 1 km resolution (EPSG:25832). Per phase: a multi-band Cloud-Optimised GeoTIFF DOY (one band per year) and BSE (per-pixel basis-spline standard error), plus CAL/GEM/VAM/PIC quality CSVs. The BSE layer is a model-internal statistical uncertainty (AGROVOC 'statistical uncertainty', c_28975); calibration is reported as PICP/MPIW at nominal 90% via 5-fold cross-validation. Pipeline Step 7. Provenance: generated with PhenoPhaseR (software concept DOI 10.5281/zenodo.18743008). AGROVOC subject anchoring (crop species + family concepts) is carried identically in the accompanying RO-Crate's schema:about.
