In the lowest layer of the atmosphere called the troposphere, we have all kinds of clouds, cumulus, stratus, cirrus, and thunderstorm clouds. The reason for this is the nature of the troposphere which means turning sphere. It is driven by convection and clouds are easily created. In the layer beyond, the stratosphere there are virtually no clouds except for those that reach into the lower stratosphere such as thunderstorms or cumulonimbus. Above the stratosphere there are the mesosphere and finally the thermosphere.

The different levels (rather layers) of atmosphere are troposphere, stratosphere, mesosphere,thermosphere and exosphere.
But all the clouds are confined to troposphere only as 90 percent of water vapour which is required for the cloud formation is available in the troposphere only .Moreover,the temperature starts inceasing with height above troposphere(in the stratosphere) and therefore the unstable condition ,required for cloud formation is absent there.
So, all the clouds are found only the lowest layer ( i.e. troposphere) only.

Most of the clouds are confined to the troposphere but there are stratospheric clouds that form in polar regions. These can be seen long after sunset and are called noctilucent clouds when this occurs. It is also in the stratospheric clouds at very low temperatures that chlorine bonds with free oxygen atoms thus diminishing the ozone layer.
