                         and renewable energy sources applications. The renewable energy 
                         assessment and forecast, in particular wind and solar energy, can 
                         be achieved through ground data measurements and radiative 
                         transfer models. Those models requires a atmospheric 
                         parameterization and the cloudiness is the main impact factor on 
                         solar irradiation at surface, and the main cause of deviations on 
                         estimated values. Concerning it, this work aims at estimating 
                         global solar irradiations from cloudiness index measured by SONDA 
                         station at Southern Spatial Observatory OES/CRS/CIE/INPE MCT. 
                         Regression techniques among solar irradiation and opaque, thin and 
                         total cloudy fractions were employed. The correlation factor was 
                         -0.76 considering just opaque cloudiness and -0,84 using total 
                         cloudiness. A longer temporal data series is necessary in order to 
                         get a more reliable multiple regression models. In addition, the 
                         relation among cloudiness and diffuse solar radiation will be 
                         analyzed in the next step.",
