                         has direct implications in meteorology, especially in the studies 
                         on the climate and its changes, affecting directly the agro

                         impacting several other sectors of the human knowledge and 
                         activities. Forecasting of incident solar radiation have a vital 
                         importance in the operation of hybrid systems for power 
                         generation, allowing an efficient management of power plants and

                         others energy resources. This work describes the development of an 
                         empirical model to estimate the diffuse solar irradiation from 
                         measurements of the global solar radiation and cloud cover. Models 
                         to estimating diffuse irradiation in surface are very valuable due 
                         to the complexity and the large costs involved in its measurement. 
                         The empirical model presented here was developed and validated by 
                         using ground data acquired in a SONDA measurement site (Brazilian

                         2004. The model have presented a mean bias error around -0,001 and 
                         root mean square error of the 0,096 . It was observed that diffuse
