A planet warms until it radiates away exactly the sunlight it absorbs. Balancing absorbed power S(1−α)/4 against εσT⁴ gives the equilibrium temperature. An emissivity below 1 represents greenhouse gases trapping outgoing infrared, raising the surface temperature.

Governing equation

Reading this result: Dropping emissivity below 1 mimics greenhouse gases: they add 32 °C on top of the -19 °C bare-rock temperature.

About this simulation

The full Energy Balance tool models a sediment plume with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a sediment plume?
Open this page and use the live Energy Balance tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a sediment plume from your own measurements.
