             abstract = "A topographical solar radiation model was tested over a set of 
                         widely varying temporal, atmospheric and geographical parameters. 
                         Digital Elevation Model (DEM) of three study sites, located in the 
                         equatorial, tropical and subtropical regions of Brazil were taken 
                         from Topodata database, a refinement of the 3 Shuttle Radar 
                         Topography Mission (SRTM), to feed Solar Analyst software package. 
                         Tests with atmospheric parameters included a comparison of default 
                         data with ground data derived from pyranometer measurements and 
                         the observation of results with data varying from clear sky to 
                         cloudy conditions. Nebulosity caused solar radiation to decrease 
                         and to reduce topographic effect into a more homogeneous 
                         distribution. The maxima/minima ratio of solar radiation results 
                         was notably decreased with increasing periods (months, semesters 
                         or year), due to a wider distribution of solar positions along the 
                         time span. Flat terrain presented narrow variation of annual solar 
                         radiation, whereas increasing slopes caused a slight increment on 
                         the observed maxima and a strong decrease in minima, thus 
                         increasing amplitude. Increasingly higher latitudes resulted in 
                         systematically lower annual solar radiation of average and flat 
                         terrain levels, and the amplitude was widened through a reduction 
                         for minima much larger than for maxima. In the equatorial area, 
                         flat terrain presented the highest levels of annual solar 
                         radiation, gradually decreasing (in absolute and relative to 
                         distribution) with latitude, until the subtropical area, where a 
                         significant portion of the mountainous areas presented higher 
                         levels than the former.",
