                         Metropolitan Area of Rio de Janeiro. The main objective of this 
                         work is to characterize observationally the diurnal and seasonal 
                         evolution of the solar radiation components in the city of Rio de 
                         Janeiro. The measurements of global and diffuse solar radiation 
                         and standard meteorological variables at the surface have been 
                         carried out regularly at the Geoscience Institute of Federal 
                         University of Rio de Janeiro since October of 2011. The 
                         microclimatic conditions show that the period 2011-2014 was warmer 
                         during most of the year and drier in summer and spring in 
                         comparison with climate normal. All solar radiation components 
                         present a well defined diurnal cycle with maximum at noon. The 
                         estimates of global and direct solar radiation indicate a great 
                         potential available for solar energy at the surface, particularly 
                         in summer. The behavior of the clearness index and diffuse solar 
                         radiation fraction is similar in summer and winter. The Angstrom 
                         formula represents properly the estimate of the monthly average 
                         daily value of global solar radiation. The sigmoid logistic 
                         function is statistically more significant in comparison with 
                         others correlation models to represent the diffuse fraction as a 
                         function clearness index.",
