Atmospheric temperature does not decrease monotonically with altitude — it follows a layered structure (troposphere, stratosphere, mesosphere, thermosphere) with local temperature minima at the tropopause (~11–16 km) and a much colder minimum at the mesopause (~85–90 km), which is the coldest region of the entire atmosphere up to the thermosphere.
Within the vertical extent from the surface to 200 km, temperature decreases through the troposphere to a local minimum at the tropopause (~-56°C near 11–16...
