PHASE: Interpolated phenological phase entry dates for major crops in Germany (collection)

This record is the collection landing page for the PHASE crop-phenology dataset. It does not itself contain the raster data: it aggregates the independent per-crop deposits into one citable unit and is the reference cited by the accompanying ESSD data descriptor. What the collection contains Each part is a standalone, versioned, citable Zenodo deposit for one crop (identified by its DWD Plant ID). Every part provides interpolated phenological phase entry dates (day-of-year) plus a per-pixel uncertainty layer (BSE), for the entire territory of Germany, 1993–2025, at 1 km resolution (EPSG:25832), produced by the PhenoPhaseR pipeline from DWD phenological observations. Crop DWD Plant ID PHASE concept DOI Winter wheat (Triticum aestivum) 202 10.5281/zenodo.19571847 Winter rye (Secale cereale) 203 10.5281/zenodo.21109411 Winter barley (Hordeum vulgare) 204 10.5281/zenodo.21134419 Winter rapeseed (Brassica napus) 205 10.5281/zenodo.21135552 Spring barley (Hordeum vulgare) 207 10.5281/zenodo.21135370 Oats (Avena sativa) 208 10.5281/zenodo.21135374 Maize (Zea mays) 215 10.5281/zenodo.21135384 Sugar beet (Beta vulgaris) 253 10.5281/zenodo.21294447 The eight PHASE deposits above are the parts of this collection; each has a matching hasPart entry in the record metadata. DOIs are the concept DOI of each crop's PHASE deposit, so the collection always resolves to the latest version. How everything is connected Software → data. Every part declares Is compiled by → PhenoPhaseR (concept DOI 10.5281/zenodo.18743008). The software record declares the reciprocal Compiles → each part. Data → data lineage. Each PHASE part is derived from its crop's upstream Filter Variants deposit (PhenoPhaseR Steps 5–6) via Is derived from / Is source of, and from the DWD input. Aggregation. Each part declares Is part of → this collection; this collection declares Has part → each part. Documentation. This collection declares Is supplement to → the ESSD descriptor (add the article DOI once it is issued). Provenance stack (per part) Each part ships an RO-Crate (ro-crate-metadata.json) with PROV-O provenance (software → filter variants → PHASE COGs), DCAT dataset descriptors, and DQV quality measurements anchored to ISO 19157-1:2023 (with the provisional fairagrodq: dimension for spatially explicit uncertainty).
