原始语种摘要: The current article investigates the relationships between solar irradiation and other climate variables of interest for viticulture; as well as with climate indexes used worldwide for viticultural zoning. Global solar irradiation was estimated through satellite imagery and, from this, photosynthetically active radiation (PAR) was calculated using a diffuse fraction model. Data were examined for six viticultural regions distributed along the Río de la Plata coastline, in South Uruguay for vintages 2011 to 2014. Results showed that available solar energy decreases from west to east in the coastline. Interannual variability is greater than spatial variability. Significant correlations were found between solar irradiation and reference evapotranspiration (R2=0.80), sunshine...
