E3SM is a state-of-the-art fully coupled model of the Earth's climate including important biogeochemical and cryospheric processes. It is intended to address the most challenging and demanding climate-change research problems and Department of Energy mission needs while efficiently using DOE Leadership Computing Facilities.

2020年1月12日 · E3SM does not show an eastward propagating OLR signal as in observations but instead shows a westward propagating OLR signal that is not coupled to a circulation feature (Figure 9b). On the other hand, SP-E3SM shows much more consistent phasing and amplitude of the OLR and wind anomalies, suggesting that the increased intraseasonal variance in ...

Specifically, our current ESM-SciDAC result shows that the inclusion of cloud LW scattering and realistic surface emission reduces all-sky OLR in the deep tropics. This can help reduce the bias of weak LW cloud radiative effect (CRE) in the E3SM. Taking cloud 3-D radiative effecting into account can affect the all-sky OLR and LW CRE in a ...

2021年6月11日 · We implement a new parameterization of heating associated with mesoscale circulations in Energy Exascale Earth System Model version 1 (E3SMv1). The parameterization improves the representation of Madden-Julian Oscillation simulated by E3SMv1 and also reduces the precipitation biases in the tropical West Pacific.

The Energy Exascale Earth System Model (E3SM) Project is an ongoing, state-of-the-science earth system modeling, simulation, and prediction project that optimizes the use of DOE laboratory resources to meet the science needs of the nation and the mission needs of DOE.

2023年12月6日 · In this study, we investigate the representation of MCSs in three configurations of the Energy Exascale Earth System Model (E3SMv1) by tracking individual storms based on outgoing longwave radiation using a new application of TempestExtremes.

Figure S7: Evolution of mean OLR fluxes (W m-2) from 1850 to 2100 for E3SM1/2 and CESM1/2 for (a) the globe, (b) 30 NH, (c) SH, (d) NH-SH. Observation-based estimates from CERES (black) are indicated. Values for each region during the CERES period are indicated in parentheses.

2020年9月23日 · The E3SM SCM library is currently comprised of 25 cases that range from widely used cases of idealized boundary layer cloud regimes of a few hours in duration to unique cases that span the duration of years to a decade (i.e., continuous forcing from Atmospheric Radiation Measurement (ARM) Southern Great Plain (SGP) site; Xie et al., 2004).

2018年7月12日 · E3SM的目标是改进当前的地球系统模拟中存在的壁垒，实现这一目标需要从3个方面取得进展：①通过在模型中开发新的流程、增加模型分辨率和提高计算性能的战略组合，更好地解决地球系统过程；②更现实地表示人类活动与自然过程之间的双向互动，特别在这些相互作用会影响美国能源需求的地方；③模型模拟和预测的不确定性。 为了解决影响美国能源行业的各种关键因素，E3SM致力于回答3个总体科学问题，推动其数字化实验计划：①水循环：水文循环 …
