RECALDE, Celso; CISNEROS, César; VACA, Diego  e  RAMOS, Cristina. Relationship between Atmospheric Transmissivity with Daily Heliophany and Extreme Temperature Difference in the Andean Equatorial Zone. Inf. tecnol. [online]. 2015, vol.26, n.1, pp.143-150. ISSN 0718-0764.

In this work, values of atmospheric transmittance coefficients using heliophany (sunshine hours) and the difference between maximum and minimum temperatures are proposed for a city located in the Andean Ecuadorian zone. First, the extraterrestrial radiation was calculated to study the reliability of the models. Later, statistical techniques were applied to meteorological data measured since June 2007 for a period of almost five years. These data were used to calculate the empirical lineal coefficients between different variables, using three models: one using heliophany and two using the difference between temperatures. The results showed that there is a more consistence relation between solar radiation and sunshine hours. In addition, it was established that it is not adequate to generalize the results to other locations even if they have similar weather characteristics.
