upper boundary of the stratosphere

The stratopause is the part of the atmosphere between the stratosphere and mesosphere. In the stratosphere the temperature gets higher the higher up you go. The stratopause is where it is warmest. On Earth, the stratopause is about 50 kilometres (31 mi) high. The temperature is about −15 °C (5 °F).[1][2][3]
