The physical dimensions of the stratosphere, viz. pressure, density, number of molecules per cubic centimeter, mean free path, molecular speed, and number of impacts, have been calculated afresh. The pressure at 100 km agrees very well with the value found empirically, hence the conclusion that the stratosphere must be warm, and some earlier assumptions furnish the corresponding vertical distribution of temperature.
