Implement option fo stochastic forcing #7

Open JanJereczek opened 7 months ago

JanJereczek commented 7 months ago

Motivation

The forcing of any ice sheet is subject to noise and implementing the possibility of providing a stochastic forcing would allow:

  1. Studying noise-induced transitions
  2. Running analyses of transitions with TransitionsInTimeseries.jl

Difficulties

The main difficulty might be to have a realistic coherence of the noise in time and space.

Resources

Dani already has scripts to generate noise as in Christian et al. (2021)

Note there is already some functionality to add white noise to forcing in the hyster module. This has slowly become an all-purpose time series forcing module as opposed to just one for hysteresis experiments. The module should probably be renamed and refactored, but this would be a natural place to add more types of noise for now.
