Abstract
Solar radiation is the main responsible of many processes of the biophysical environment Temperature changes snow melt dynamics carbon sequestration evaporation from soils plants and open water bodies are explained by the amount of radiation received in a surface Lack of direct observations and insufficient record length limit the ability to use global solar radiation information for resource use management and planning Based on the general equation of Bristow and Campbell we propose a modification that allows us to better represent atmospheric transmissivity as a function of routine meteorological variables and improve estimates of global solar radiation in Mediterranean and semi arid areas The improved BristowCampbell model IBC is easy to use in any location where measurements of temperature precipitation and relative humidity are available and present a simple solution that can be used as proxy for relative humidity in case that variable is not been measured
