Abstract : The difficulties in distinguishing between an upper and lower Venusian atmosphere are pointed out. The lack of reliable basic data, such as surface pressure and temperature, temperature gradients, gaseous and particulate composition, large and small scale air motion, related to the denser parts of the atmosphere are noted. The wide variation of surface pressure estimates, ranging between 3 and 1000 atmospheres, advanced by various authors recently is displayed graphically. No critique of these is attempted because the corresponding models are not sufficiently well defined nor thoroughly analyzed. (Author)
