Regression of the Scattered Radiation Intensity with Precipitable Water Depth and Relative Atmospheric Mass
The precipitable water influences the radius size of the absorbent continental particles and maritime aerosols. The precipitable water depth and the scattered irradiance intensity were measured at the Atmospheric Physics Laboratory of the University of Patras during sunny days, at constant solar elevations, in the time period 2006–2009, exhibiting seasonal variation with a summer maximum and a winter minimum. The data analysis results in a higher scattered irradiance summer maximum and a lower winter minimum during the prevalence of continental air masses than that of maritime air masses. Two families of regression curves of the scattered irradiance intensity with precipitable water depth are being obtained, one for continental and one for maritime air masses. The aim of this work is the computation of the scattered irradiance intensity from the origin of the air masses, and the values of the precipitable water depth and relative atmospheric mass.
