The van der Waals state equation for atmosphere is determined from the critical temperature and critical pressure of the air gases. The meteorological radiosonde measures atmospheric pressure, temperature, and other meteorological variables, at several altitude levels. Therefore, the diurnal and nocturnal vertical profiles of the monthly average density of the atmosphere were constructed, considering the atmospheric system as an ideal gas and also as a van der Waals gas. For this purpose, the radiosonde data of the atmosphere of the metropolitan region of Natal-RN, Brazil, from 2010 to 2017, with altitude ranging from 50m to 10km.
