title: Orbital-accelerated transient simulations of glacial-interglacial climate cycles for the last 800,000 years dataset

description: Data related to the manuscript titled "Climate change in the glacial-interglacial cycle: numerical simulations of transient climate forcing over the last 800,000 years." We utilized the CESM1.2.2 model to simulate the climate over the past 800,000 years. The main climate boundary conditions modified include greenhouse gases, ice sheets, and orbital parameters. A suite of experiments with full forcing and three sets of component forcing were conducted.
