PPMLR Simulations

These are the six PPMLR MHD simulation files used in the CMEM project. They are here courtesy of T. Sun from the National Space Science Centre in Beijing.PPMLR (Parabolic Piecewise Method with Lagrangian Remap) is a magnetohydrodynamic (MHD) code developed in China used for creating global simulations of the Earth's magnetospheric environment. In this context, the results of a PPMLR simulation have been compared with an exospheric neutral density model in order to calculate the soft X-ray emissivity expected around the Earth's magnetosheath. It is these PPMLR-emissivity simulations uploaded here.These simulations have been used for the upcoming publication titled: "Modeling the Magnetospheric 3D X-ray emission from SWCX using a Cusp-Magnetosheath Emissivity Model," which is being submitted to the Journal of Geophysical Research: Space Physics. The simulations were used to develop and test a new emissivity model called CMEM (Cusp Magnetosheath Emissivity Model) that will be used for magnetopause detection for the upcoming Solar Wind Magnetosphere Ionosphere Link Explorer (SMILE) mission.<br>Update 1st Oct 2024: The FITS versions of these files have also now been uploaded. <br>本数据集包含CMEM项目中使用的6个PPMLR磁流体动力学（MHD）模拟文件，由北京国家空间科学中心的T. Sun友情提供。 PPMLR（Parabolic Piecewise Method with Lagrangian Remap，即带拉格朗日重映的分段抛物法）是一款由中国自主研发的磁流体动力学代码，用于开展地球磁层环境的全球模拟研究。 本研究中，研究人员将PPMLR模拟结果与外层大气中性密度模型进行对比，以计算地球磁鞘周围预期产生的软X射线发射率，本数据集上传的正是该PPMLR模拟得到的发射率数据。 这些模拟文件已用于即将投稿至《地球物理研究杂志：空间物理学》（Journal of Geophysical Research: Space Physics）的论文"Modeling the Magnetospheric 3D X-ray emission from SWCX using a Cusp-Magnetosheath Emissivity Model"。 本模拟被用于开发和测试一款名为CMEM（尖峰磁鞘发射率模型，Cusp Magnetosheath Emissivity Model）的新型发射率模型，该模型将为即将实施的太阳风-磁层-电离层连线探测器（SMILE）任务提供磁层顶探测支持。 2024年10月1日更新：本数据集现已同步上传上述文件的FITS格式版本。
