Model data for "Simulation of the climatic conditions required for the existence of ice sheet on the Tibetan Plateau"

Dataset for Modeling the Climatic Conditions Required for the Existence of an Ice Sheet on the Tibetan Plateau This dataset originates from the study “Simulation of the Climatic Conditions Required for the Existence of an Ice Sheet on the Tibetan Plateau,” and provides detailed simulation data related to the research. The dataset includes the following four core components: 1. Atmospheric Circulation Simulation Data (CAM5 Model) Contains monthly mean climate variable outputs from the CAM5 model under different glacier cover scenarios: Pre-Industrial Control Experiment: V2Fpid_control.cam.h0.monthly.nc – represents the baseline climate state. Last Glacial Maximum (LGM) Baseline Experiments: V2Flgm_istp_00.cam.h0.monthly.nc to V2Flgm_istp_100.cam.h0.monthly.nc – comprise 11 LGM climate simulations with glacier coverage ranging from 0% to 100%. 2. Ice Sheet Model Simulation Data (PISM Model) Ice sheet evolution results simulated by the PISM model, driven by climate forcing derived from CAM5 outputs: Ice Thickness Distributions Under Various Glacier Coverage Scenarios: PISM-TPG-LGM-00%.nc to PISM-TPG-LGM-100%.nc – equilibrium ice thickness corresponding to the 11 glacier coverage scenarios. Modern Climate Baseline: PISM-TPG-PID.nc – glacier distribution under pre-industrial climate conditions. 3. Ice Sheet–Climate Feedback Experiment Data Sensitivity experiments examining the effects of ice sheet albedo and thickness under full glacial coverage: Combined Ice–Climate Feedback Experiment: V2Flgm_using_TPG-LGM-100%_both_thk_alb.cam.h0.monthly.nc – includes both ice thickness and albedo effects. Albedo-Only Feedback Experiment: V2Flgm_using_TPG-LGM-100%_only_alb.cam.h0.monthly.nc – considers only the albedo effect. Thickness-Only Feedback Experiment: V2Flgm_using_TPG-LGM-100%_only_thk.cam.h0.monthly.nc – considers only the ice thickness effect. 4. Temperature–Precipitation Configuration Dataset for Glacier Development Synthesized critical climatic thresholds for glacier development over the Tibetan Plateau, based on multiple simulation results: Core Data File: TAS_PR_configuration_dTS_dPR_for_Full_cover_TPG_and_icesheet-thickness-thk.nc Variables Included: temperature threshold (°C) and precipitation change threshold (%) required for glacier development, along with corresponding ice thickness (m). This dataset offers a comprehensive numerical simulation foundation for understanding the paleoglacial evolution of the Tibetan Plateau, ice sheet–climate feedback mechanisms, and the critical temperature–precipitation conditions for glacier development.
