Planetary Trenberth Diagrams

A Trenberth diagram shows the movement of energy within a planetary system. The energy comes from the Sun and undergoes a series of reflections, absorptions and emissions through interactions with the planet's atmosphere and surface. This should result in a net change as close to zero as possible. Otherwise the system is either absorbing or emitting energy, which creates a lasting effect over time, resulting in climate change.[more]
This model lets you vary incoming solar radiation and atmospheric reflection levels of the Earth, Mars or Venus to show the impact on internal climate.[less]
