Restart

The optional restart parameter is NULLNone by default, which begins the simulation at a preindustrial steady state. Alternatively, restart can be set to a data framedictionary of lists containing the initial state of the climate; if more than one row, longterm initializes with the last row. Most often, this will be the output of a previous simulation. Arbitrary starting states can be constructed, in the format of longterm output, and fed to restart, but the preferred method of creating perturbed – i.e., non-preindustrial states – is with the use of the sources input listdictionary.
