The regional frequency analysis (RFA) is a useful tool that allows, using statistics analysis, to solve the problem of data scarcity in time by increasing data in space. In the last decades, the Daily Temperature Range (DTR), widely used for the estimation of relevant hydrometeorological variables such as Solar Radiation or Reference Evapotranspiration, has experienced an increasing importance on the scientific field to analyse and study phenomena as climate change. In the present work, the RFA of DTR timeseries from 193 meteorological stations in Andalusia has been carried out in order to analyse the similarity of the series and to establish homogeneous regions. As a previous step, different quality control methods have been applied to DTR data, as prerequisite of its use, and to ensure its verisimilitude. In the ARF, the discordant stations have been rejected, and the potential homogeneity of the rest of stations has been analysed, being Andalusia a heterogeneous region. Later, using the multifractal parameters of the stations, they were grouped into sub-regions, repeating the procedure up sometimes, in none of them finding homogeneous sub-regions.
