The expected parameters in Stratopause are; Temperature: -15 degrees Celsius, Pressure: 1 milibar and Water vapor concentration: cannot be determined.
Explanation:
"Stratopause" is the interaction between the ionosphere and the stratosphere. It is 50-55 km high above the earth surface that is why temperature is very less approximately -15 degrees Celsius (5 degrees Fahrenheit). As it is a thin layer separating the stratosphere and ionosphere actual water vapor concentration cannot be determined. The atmospheric pressure is around 1/1000 of the pressure at sea level.
