In this work, doctoral thesis can be highlighted briefly the following aspects: they have conducted an extensive bibliographic review of the different existing models of solar irradiance BROADBAND AND A COMPARATIVE ANALYSIS OF ALL THESE TO BE ALLOWED TO BUILD A MODEL COMPLETE AND CONSISTENT AND UPDATED solar irradiance FOR ALL OF THE BAND TO HEAVEN DESPEJADOS.SE HAVE ESTABLISHED TWO METHODS OF SELECTION FOR ACTION STATUS clear sky that part of the value of the experimentally measured irradiance BROADBAND TO SORT, HE HAS VERIFIED THE EFFECTIVENESS of these methods that enable automation of sorting CLASIFICACION.SE DATA AND HAS ESTABLISHED A NEW METHOD FOR DETERMINING THE RATE OF B Angstrom turbidity atmosphere HAVE THE ADVANTAGE OF ITS APPLICATION TO REQUIRE ONLY THE ACTIONS OF EXPERIMENTAL Irradiance GLOBAL AND DIFFUSE irradiance on a horizontal plane. ERA so far not possible to determine the turbidity of these measures EXPERIMENTAL MEASURES THAT ARE CURRENT AND RADIATION MAS which are available in many places and periods in many years. Studies have been conducted SENSITIVITY OF PROPOSED NEW METHOD OF DETERMINATION OF turbidity and a method to date and to put similar LOUCHE DENOMINATOR OF METHOD TO BE USED FOR REFERENCE. It is also a comparative analysis of results and errors. As a result of this analysis to have been used experimentally measured in Valencia and Seville, the new method has been enhanced in Validate and endorsed as more desirable than the previous one in most circumstances given the data currently available experimentally more. ADAPTATION TO A NEW METHOD OF SPECTRAL SIMPLE PROGRAM PREPARED BY BIRD AND RIORDAN HAS SHOWN IN 1986
