Data from: A variety-specific analysis of climate change effects on California winegrapes

<div>This folder, titled "Data," contains the MATLAB code, final products, tables, and figures used in Parker, L.E., Zhang, N., Abatzoglou, J.T. <em>et al.</em> A variety-specific analysis of climate change effects on California winegrapes. <em>Int J Biometeorol</em> <strong>68</strong>, 1559–1571 (2024). https://doi.org/10.1007/s00484-024-02684-8  </div> <p><br></p> <ul><li><strong>Data Collection:</strong> Climatological data (daily maximum and minimum temperatures, precipitation, and reference evapotranspiration) were obtained from the gridMET dataset for the contemporary period (1991-2020) and from 20 global climate models (GCMs) for the mid-21st century (2040-2069) under RCP 4.5.</li><li><strong>Phenology Modeling:</strong> Variety-specific phenology models were developed using published climatic thresholds to assess chill accumulation, budburst, flowering, veraison, and maturity stages for the six winegrape varieties.</li><li><strong>Agroclimatic Metrics:</strong> Fourteen viticulturally important agroclimatic metrics were calculated, including Growing Degree Days (GDD), Cold Hardiness, Chilling Degree Days (CDD), Frost Damage Days (FDD), and others.</li><li><strong>Analysis Tools:</strong> MATLAB was used for data processing, analysis, and visualization. The MATLAB code provided in this dataset includes scripts for analyzing climate data, running phenology models, and generating visualizations.</li></ul><ul><li><strong>MATLAB Code:</strong> Scripts and functions used for data analysis and modeling.</li><li><strong>Processed Data:</strong> Results from phenology and agroclimatic analyses, including the projected changes in phenological stages and climate metrics for the selected varieties and AVAs.</li><li><strong>Tables:</strong> Detailed results of phenological changes and climate metrics, presented in a clear and structured format.</li><li><strong>Figures:</strong> Visual representations of the data and results, including charts and maps illustrating the impacts of climate change on winegrape development stages and agroclimatic conditions.</li></ul> <p><br></p> <div><strong>Research Description:</strong> This study investigates the impacts of climate change on the phenology and agroclimatic metrics of six winegrape varieties (Cabernet Sauvignon, Chardonnay, Pinot Noir, Zinfandel, Pinot Gris, Sauvignon Blanc) across multiple California American Viticultural Areas (AVAs). Using climatological data and phenology models, the research quantifies changes in key development stages and viticulturally important climate metrics for the mid-21st century.</div> <p><br></p>
