             abstract = "Earlier studies have demonstrated that the Northeastern Brazilian 
                         region (NEB) has the most abundant solar energy resource of the 
                         Brazilian territory due to its geographical location, and its 
                         environmental characteristics. However, the spatial and seasonal 
                         variability was little evaluated. This work investigated the 
                         surface solar irradiation variability and trends based on a 
                         statistical analysis of the ground data acquired in automated 
                         weather stations operated by the Brazilian Institute of 
                         Meteorology. A data quality control procedure was accomplished 
                         according to WMO criteria to avoid suspicious data. The results 
                         pointed out a remarkable variability in seasonal and annual 
                         scales. The cluster analysis provided five regional patterns 
                         presenting quite interesting temporal complementary regimes for 
                         the incoming solar irradiation. The surface solar irradiation 
                         achieves the highest values in the Southeastern area of NEB and 
                         the lowest in the Western area during the austral summer. The 
                         annual and seasonal trends of the surface solar irradiation were 
                         investigated using the Mann-Kendall method and the Sen technique. 
                         The surface solar irradiation in the Southeastern area of NEB is 
                         decreasing by 50 Wh/m2 /year since 2008. On the other hand, it is 
                         increasing around 40 Wh/m2 /year in the semi-arid area at the same 
                         timeframe.",
