TORREZ, R.; BURGOA, A.  and  RICALDI, E.. MODELS ESTIMATING THE SOLAR RADIATION FOR BOLIVIA'S CENTRAL ALTIPLANO REGION. Revista Boliviana de Física [online]. 2013, vol.23, n.23, pp.1-7. ISSN 1562-3823.

We validate the Bristow Campbell (BC) y de Hargreaves-Samani (HS) estimation models for solar radiation with recent data obtained from the meteorological station located in the Universidad Mayor de San Andrés facilities at Patacamaya (17^o15′S, 68^o48′W y 3890 a.s.l.) for the August 2010 to July 2012 period. The purpose of this validation was to apply these methods to evaluate the solar resources in the central Bolivian Plateau. We chose the BC and HS methods because of the easiness in the input required data, i.e., maximum and minimum daily temperatures, which are the commonly registered data in all the stations of the Meteorology and Hydrology National Service, as well as in other public and private institutions. The physical constants used in these methods were evaluated from the general expressions of the solar astronomy. For a practical purpose we present a plot of the immediate extraterrestrial solar radiation for each month and for the relevant latitudes in the Plateau region. The results (considering the precision of the model) are among those that are commonly accepted given the scarce data. The result of this work for the atmosphere transmitance is 0.166, which is consistent with the referred values in the technical literature for the Bolivian Plateau region.
