New formulae to evaluate the atmospheric layers of precipitable water and gases, applicable in solar radiation computing models

2014 The theoretical formulae we propose use the ground values of air pressure, temperature and relative humidity, parameters measured by most of the meteorological stations. The results were found to be in good agreement with those obtained from several semi-empirical formulae proposed by other authors. To compute more exactly the precipitable water layer it was established a relation which is more general than the existing empirical corrections. The theory was compared with the results obtained by using six atmospheric models based on measurements. It was found out a good concordance. Revue Phys.
