Analysis-ready hyperspectral grape dataset for sequential vineyard-management validation and limited-reference temporal updating (VITIMPACT 2026)

Frozen analysis-ready dataset supporting a sequential validation study of hyperspectral vineyard phenotyping in Garnacha Tinta during the 2026 VITIMPACT campaign. The workbook contains 240 plot-date sample records from six vineyard-management treatments and four randomized blocks, calibrated sample-level mean spectra from Specim FX10 (224 bands, 400.67–997.99 nm) and FX17 (112 bands, 937.33–1718.44 nm), 13 laboratory reference attributes for 135 chemically analysed samples, wavelength definitions, QC metadata and the frozen registry of 15 reference samples used for limited-reference temporal updating. The principal analytical populations are Temporal216, Primary120, SameDate132, All135, Anchor15 and Operational105. Raw hyperspectral cubes and the complete raw-image extraction environment are not included; reproducibility begins at archived sample-level mean spectra and laboratory reference values.
