N_surplus_typologies_Europe

First numbered release containing: All input datasets (Excel format) used to produce Figures 1–5 of the main manuscript: including nitrogen surplus data, typology-specific inputs/outputs, and scenario projections. R scripts to reproduce each figure, including: Data preprocessing Statistical modeling (e.g., linear regression, yield response fitting) Visualization generation using ggplot2 Publication-quality output figures (PDF format) including: Historical nitrogen surplus time series Typology classification and evolution Scenario-based nitrogen surplus reduction projections Yield response curves Readme documentation describing all data columns, modeling assumptions, and plotting procedures. This release enables reproducibility of the nitrogen surplus typologies and scenario analysis presented in the study.
