Resumen:
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
duration (R2
=0.71), maximum (R2
=0.48) and mean temperature (R2
=0.39). A negative
relationship was found for relative humidity (R2
= 0.40). Energy accumulation over the
growing period showed a similar behaviour to the Adapted Heliothermal Index
(R2
=0.98), whereas mean daily irradiation for February was negatively correlated with
the adapted Dryness Index (R2
= 0.53). At the vineyard scale, a relationship between PAR
and global solar irradiation of 48.3% was determined. Due to the limitation to the use of
solar energy imposed by high temperatures, the amount of energy used by the vineyard
represented a 34.3% of the global solar irradiation. Satellite images allowed for an
accurate estimation of solar irradiation in locations where no ground observations are
available. Moreover, this information can be used for viticultural zoning and for
determining interannual variation of environmental conditions and for analyzing their
influence on plant development and vintage quality.
