TL;DR: A new version of the atmosphere-ocean general circulation model cooperatively produced by the Japanese research community, known as the Model for Interdisciplinary Research on Climate (MIROC), has recently been developed.
Journal ArticleDOI

TL;DR: The 6th version of the Model for Interdisciplinary Research on Climate (MIROC), called MIROC6, was developed by a Japanese modeling community as discussed by the authors, and the results show that the overall performance of mean climate and internal climate variability in MirOC6 is better than that in MIRoc5.
Journal ArticleDOI
A simulation of the global distribution and radiative forcing of soil dust aerosols at the Last Glacial Maximum
TL;DR: In this article, an integrated simulation of the global distribution and the radiative forcing of soil dust aerosols at the last glacial maximum (LGM) is performed with an aerosol climate model, SPRINTARS.
Journal ArticleDOI
Set-up of the PMIP3 paleoclimate experiments conducted using an Earth system model, MIROC-ESM
Tetsuo Sueyoshi,Rumi Ohgaito,Akitomo Yamamoto,M. O. Chikamoto,Tomohiro Hajima,H. Okajima,Masakazu Yoshimori,Manabu Abe,Ryouta O'ishi,Fuyuki Saito,Shingo Watanabe,Michio Kawamiya,Ayako Abe-Ouchi,Ayako Abe-Ouchi +13 more
TL;DR: In this article, the authors present the implementation of the MIROC-ESM, an Earth system model based on the global climate model, for the Coupled Model Intercomparison Project (CMIP5/PMIP3) phase 3 using the mid-Holocene, the Last Glacial Maximum, and the Last Millennium experiments.

TL;DR: In this paper, a synthesis of observational and model data was used to reconstruct atmospheric dust concentrations in the Holocene and Last Glacial Maximum, showing that the impact of aerosols in polar areas is underestimated in simulations for dustier-than-modern conditions.
