Abstract

The objective of the Project is to carry out an operational test of a computer program developed in the Botucatu solar radiometry station for the treatment of database with solar radiation. As application of the program, we will carry out modeling studies with diffuse solar radiation, verifying existing models and proposing an estimative model for the city of Botucatu, São Paulo. The database to be used in the study consists of the global and diffuse radiations monitored by two methods (difference and ring-shadow) in the period from June 1994 up to the present time. (AU)
