+ | ====== What model runs might be relevant ====== | ||
+ | There are a lot of different model runs available as part of PMIP. In fact the amount of output can be a bit overwhelming at first. On important distinction is the different between *transient* and *equilibrium* simulations. All climate models are run forwards in time and write output every month/day. So this distinction really relates to the forcing inputs, and the climate response to them. From a practical perspective, | ||
