Input

The Longterm Climate Model can be run with no arguments as follows.

• R
• Python

output <- longterm()

output = longterm.run();

This, however, is a boring use of longterm, as it will simply return the steady-state preindustrial climate. More interesting simulations are generated by setting some of the optional arguments, especially sources. For example, you could run a simulation in which a 1 W/m² top-of-atmosphere radiative forcing is turned on and kept on.

• R
• Python

output <- longterm(sources(rad=1))

output = longterm.run(sources({"rad":1}));

Details on all of longterm’s optional input variables can be found in the pages below.
