                         energy which is continuously received from the sun has led more 
                         recently to increased efforts toward a better knowledge of its 
                         disposition to satisfy world wide energy demands. There is no 
                         unique solution for solar energy utilization, since the local 
                         requirements depend on climatological archievements and local 
                         availability of materials and technicians. As a matter of fact the 
                         global availability of solar energy is an immense resource when 
                         compared with conventional resources. For solving present and 
                         future problems strong efforts have to be initiated in collecting 
                         and estimating data for availability of solar radiation with high 
                         local and temporal resolution. Since the implementation of the 
                         brazilian network of meteorological observing stations the 
                         sunshine duration has been recorded, by the Campbell-Stokes 
                         recorder. There exist in our days various limitations on the 
                         utilization of this equipament in the manner it is being performed 
                         in the brazilian network. One of the facts affeting the 
                         observations of sunshine recorder is the type and quality of cards 
                         that are being used by the different Instituitions that operate a 
                         network. The author analised the characteristics of the twelve 
                         different types of cards, concerning: color, dimensions, time of 
                         burning and overburning as well as the value of the minimun 
                         radiation flux necessary to start burning. At the same time the 
                         present study aims at providing a semi-empirical model for the 
                         estimation of daily global solar radiation and the components of 
                         direct and diffuse radiation in the model methods of 
                         parametrizations such as Rayleigh and Mie scattering, absorption 
                         due to water vapour, C02, 03 and oxigen were used. In the model, 
                         it was considered the fluxes of absorption and scattering by 
                         aerosols and clouds. The entries in the model were the 
                         meteorological variables observed in the met-station at the 
                         surface: atmospheric pressure, air temperature air moisture, cloud 
                         types and cloudiness. The model was tested for seven places a0d 
                         showed a relative error smaller than the one give by pyranometer 
                         (5%).",
