Tropopause

Tropopause, marks the boundary between the troposphere and
stratosphere, here temperature is generally considered relatively
constant with increasing altitude

Commercial Aircrafts

Commercial aircraft, use the upper reaches of the troposphere.
This allows them to take advantage of the low air density to achieve
higher speeds and lower fuel consumption. In addition, this altitude
is free of intense weather phenomena and birds.

Weather Phenomena

Radiosonde

A radiosonde is a battery-powered, balloon-borne instrument package that measures atmospheric conditions like temperature, pressure, humidity, and wind, transmitting the data via radio to a ground station.

Military Aircraft / Supersonic Jets

Military flights use the area between the troposphere and the
stratosphere, known as the tropopause. In this layer, the density
is even lower, so their jet engines are at their most efficient.

Noctilucent Clouds

Noctilucent clouds (NLCs) or night-shining clouds are the highest clouds in the Earth's atmosphere, and are visible during twilight in the summer. They are made of ice crystals that form in the mesosphere, the third layer of the Earth's atmosphere.

Polar Stratospheric Clouds

Polar stratospheric clouds (PSCs), also known as nacreous or mother-of-pearl clouds, are high-altitude, icy clouds that form in the polar stratosphere during winter when temperatures drop below -78°C, playing a role in ozone depletion.

Auroras

Aurora also called the "northern lights" (aurora borealis) in the north and "southern lights" (aurora australis) in the south, caused by charged particles from the sun colliding with gases in the atmosphere.
