Mean sea level (MSL) (often shortened to sea level) is an average level of the surface of one or more of Earth's oceans from which heights such as elevation may be measured.
In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL) is a height measured with respect to the underlying ground surface. This is as opposed to altitude/elevation above mean sea level (AMSL), or (in broadcast engineering) height above average terrain (HAAT).

Which level do you use in the windy?(exp.cloud section)

Thank you for your interest...

@marko said in Altitude selection:

When choosing an altitude (on windows firefox) with a click on altitude level and then trying to move with keyboard keys "left" and "right" it changes Altitude and timeline at same! so presing right increases time and increases altitude.

Thanks for windity,
Marko
