It is sandwiched between the surface of the earth at its bottom point and at the top of the troposphere is the tropopause. ... Water vapor it important as it will absorb solar energy and thermal radiation from the surface of Earth, thus regulating the air temperature.

Why is tropopause important in aviation?

The location of the tropopause is of interest to flight crew because it indicates the altitude at which temperature becomes constant with increasing altitude, which is an import factor in performance and fuel calculations.

Why troposphere is an important layer?

The study of the troposphere is very important because we breathe the air in this layer of air. ... Tropospheric processes, such as the water or hydrologic cycle (the formation of clouds and rain) and the greenhouse effect, have a great influence on meteorology and the climate.
