Abstract: This work proposes a step-by-step data gathering and processing methodology of solar irradiance measurements for producing filtered and continuous data series for the assessment of solar energy availability. The method is applied to data from 8 measuring stations in the southern region of Portugal. With the current amount of stations and as the measurement period continuously increases, it allows a better regional characterization of DNI availability and creates conditions for in depth studies. This infrastructure has high relevance for the region, known for its high annual GHI availability and its reduced inter-annual variability, thus a high annual DNI availability is expected.
