PMIP4 experiments using MIROC-ES2L Earth system model

Abstract. Following the protocol of fourth phase Paleoclimate Modelling Intercomparison Project (PMIP4), we performed numerical experiments targeting distinctive past time periods using Model for Interdisciplinary Research on Climate, Earth System version 2 Long-term simulations (MIROC-ES2L), which is an system model. Setup and basic performance are presented. The Last Glacial Maximum was one most extreme climate states during Quaternary conducting modeling this period has long been a challenge paleoclimate community. We conducted experiment with spin-up nearly 9000 years. Globally, there reasonable agreement between anomalies relative to present day derived from model climatology those proxy data archives, while some regional discrepancies remained. By changing orbital greenhouse gas forcings, two interglacial periods: 6000 127 000 years before present. were qualitatively consistent variations in solar forcing. However, smaller than suggesting that processes play role climates remain lacking state-of-the-art transient 850 1850 CE 2014 CE.
