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, you should be looking at the long-term statistics of the equilibrium simulations, and the temporal variations in the transient simulations. There are more details and links below, but a quick division of the experiments is... * **PMIP4/CMIP6 Equilibrium Simulations** * **piControl** (Preindustrial): //The control run that all the climate changes can be calculated from// * **abrupt4xCO2** (Instantaneous quadrupling of carbon dioxide): //An idealized global warming experiment (primarily included for calculating the climate sensitivity)// * **midHolocene** (6,000 yrs ago): //Useful for identifying impacts of orbital forcing// * **lgm** (The last glacial maximum at 21,000 yrs ago): //The archetypal cold climate state// * **lig127k** (Last Interglacial, 127,000 yrs ago): //Peak of the warm period prior to last glaciation// * **Eoi400** (Pliocene, 3,205,000 years ago): //warm conditions before any Northern Hemisphere glaciation (minimal continental drift)// * **DeepMIP** (Eocene & Paleocene, 50-60 million yrs ago): //Warm climates with carbon dioxide concentrations similar to end of century projections (continents drifted, PMIP-only)// * **PMIP4/CMIP6 Transient Simulations** * **1pctCO2** (Carbon dioxide concentrations increase by 1% per year): //An idealized global warming experiment (primarily included for calculating the transient climate response)// * **historical** (1850CE onwards): //Free-running simulations of industrial era (so climate variability's phase/sign does not match observations, but its statistics should)// * **past1000** (last millennium, 850CE onwards): //Free-running simulations seeing 1000+ years of climate forcings// * **LDv1** (last deglaciation, 21,000 years ago to present): //Very-long simulation that encompasses all forcings (PMIP-only)// * **Other Transient Simulations** //There are several other long palaeoclimate simulations that my be useful// * **[[https://www.earthsystemgrid.org/project/trace.html|TraCE]]** This simulation runs from 22,000 years before present (22ka) to 1990 CE as well as single-forcing sensitivity simulations of varying lengths.
