论文摘要
我们探索了Alfven波太阳大气模型（AWSOM）的模型性能，并具有光电矢量磁场的近实时（NRT）概要图。这些图是通过在太阳能动力学天文台（SDO）上吸收来自Heliose震动磁成像仪（HMI）的数据而产生的，它使用在国家太阳天文台（NSO）开发的另一种方法，以提供近乎同时的数据源来驱动数值模型。 Here, we apply these NSO-HMI-NRT maps to simulate three Carrington rotations (CRs): 2107-2108 (centered on 2011/03/07 20:12 CME event), 2123 (integer CR) and 2218--2219 (centered on 2019/07/2 solar eclipse), which together cover a wide range of activity level for solar cycle 24. We show simulation results, which reproduce both从低电晕的极端紫外发射（EUV）同时匹配1 Au处的原位观测，并量化这些地图的总未签名开放磁通量。
We explore model performance for the Alfven Wave Solar atmosphere Model (AWSoM) with near-real-time (NRT) synoptic maps of the photospheric vector magnetic field. These maps, produced by assimilating data from the Helioseismic Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO), use a different method developed at the National Solar Observatory (NSO) to provide a near contemporaneous source of data to drive numerical models. Here, we apply these NSO-HMI-NRT maps to simulate three Carrington rotations (CRs): 2107-2108 (centered on 2011/03/07 20:12 CME event), 2123 (integer CR) and 2218--2219 (centered on 2019/07/2 solar eclipse), which together cover a wide range of activity level for solar cycle 24. We show simulation results, which reproduce both extreme ultraviolet emission (EUV) from the low corona while simultaneously matching in situ observations at 1 au as well as quantify the total unsigned open magnetic flux from these maps.
