It is not usual to have high frequency solar radiation measurements at a site, so the use of synthetically generated series could be a practical and useful alternative, but the assimilation of sites with similar intra-hourly variability is difficult. In this work, we try to characterize the high-frequency behaviour of solar radiation in locations with similar Köppen-Geiger climatology by combining several previously published techniques. For this, 3 years of one-minute measurements of direct normal irradiance (DNI) and global horizontal irradiance (GHI) of sites with different climatology have been evaluated. The obtained results are compared with others previously published, and with a site with a climate similar to one of those selected.
