Resumen:
Firstly, the importance of the solar energy potential in Salta has been highlighted by the government in its Provincial Renewable energy Plan and by worldwide researchers. Yet solar radiation estimations are available mainly in low spatiotemporal resolutions and studies that characterize the temporal variability are scarce.Secondly, to design and evaluate solar energy devices is highly-recommended to count with ground measured historical data of global solar radiation from calibrated and maintained meteorological stations. However,high costs of installation, maintenance and communication to centralize the data have promoted the development of different models to estimate the global solar radiation from available data and the use of solar radiation data derived from satellite imagery.For both reasons, in this work we evaluate global solar radiation from the ERA5 reanalysis data set provided by the European Centre for Medium-Range Weather Forecasts (ECMWF) and the Meteosat second generation derived data set provided by Land Surface Analysis Satellite Applications Facility (LSA-SAF). Theseare compared with data from four pyranometers distributed around the region in a period of seven years.
