AOGCM initialized from a spun-up piControl with constant-in-time forcing of orbital parameters and greenhouse gas concentrations indicative of 127,000 years before present; use of components AER, CHEM, BGC is allowed, yet it must be ensured that relevant greenhouse gas concentrations in the atmosphere stay constant at the specified values throughout the simulation; relevant references: Otto-Bliesner et al.

"description": "esm-flat10-cdr is newly introduced for CMIP7 as an emissions-driven idealised experiment to quantify sensitivity of the earth system to CO2 removal / negative emissions. It requires fully-coupled AOGCM and BGC models with carbon cycle “emissions-driven” The esm-flat10-cdr experiment branches from year 100 of the esm-flat10 simulation, but with CO2 emissions set to decline linearly to zero after 50 years, decrease further (becoming negative) over the next 50 years (reaching -10 PgC/yr) and then remain constant at -10 PgC/yr for a final 100 years. It serves as an emissions-driven experiment to diagnose the reversibility of the Earth system due to carbon dioxide removal. By the end of the simulation the cumulative emissions over 300 years will be exactly zero – the same amount of CO2 has been removed as was added. Used with the partner experiments esm-flat10 and esm-flat10-zec it forms a vital part of assessment of TCRE, ZEC and reversibility. In particular these experiments make assessment of ZEC easier than CMIP6 because: the experiment is emissions-driven from the outset and does not require a change in configuration at the branch point and the branch point is common across all models. more details and analysis can be found here: https://egusphere.copernicus.org/preprints/2023/egusphere-2023-2127/ https://egusphere.copernicus.org/preprints/2024/egusphere-2024-3356/ this experiment is an evolution of the CDRMIP simulations from CMIP6: https://gmd.copernicus.org/articles/11/1133/2018/",

"description": "esm-flat10 is newly introduced for CMIP7 as an emissions-driven idealised experiment to quantify sensitivity of the earth system to CO2 emissions. It requires fully-coupled AOGCM and BGC models with carbon cycle “emissions-driven” The esm-flat10 experiment branches from a stable esm-piControl simulation, with a constant annual prescribed anthropogenic flux of carbon of 10PgC/year into the atmosphere, with globally homogenous emissions for initial (minimum) period, 0-150 years. Longer runs - 300 years – are recommended. It serves as an emissions-driven experiment to diagnose the Transient Climate Response to cumulative Emissions (TCRE), which is the warming from pre-industrial levels observed after the emission of 1000PgC in a transient scenario.
