The core experiment includes the evolving orbital conditions, ice sheets, greenhouse gases, and meltwater. The other experiments adopt a factorized forcing scheme to allow isolating each of these forcings separately. These experiments extend the publicly available TraCE simulations, available on the CDG and downloaded by the research community, using the higher resolution iCESM1.2 model that includes predictive simulation of water isotopes in the atmosphere-ocean-land-runoff-sea ice system. All simulations are performed with the atmosphere-ocean-land-sea ice coupled CESM1.2 at the nominal 2-degree latitude/longitude for the atmosphere and land models, and 1-degree for the ocean and sea ice models. The simulations contain climate stable water isotope output from all model components, plus carbon, neodymium, protactinium, and thorium isotopes in the ocean model output. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral CESM > NCAR Community Earth System Model U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY > SPECIFIC HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > U/V WIND COMPONENTS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND DYNAMICS > VERTICAL WIND VELOCITY/SPEED EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > LIQUID PRECIPITATION > RAIN EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION PROFILES > LATENT HEAT FLUX U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 0001-01 0001-12 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 165247535.45 https://gdex.ucar.edu/datasets/d651022/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d651022/dataaccess/ https Data Access Related Link download none asNeeded
