Solar wind modeling with the Alfven Wave Solar atmosphere Model driven by HMI-based Near-Real-Time maps by the National Solar Observatory

We explore model performance for the Alfvén Wave Solar atmosphere Model (AWSoM) with near-9 real-time (NRT) synoptic maps of the photospheric vector magnetic field. These maps, produced by 10 assimilating data from the Helioseismic Magnetic Imager (HMI) onboard the Solar Dynamics Obser-11 vatory (SDO), use a different method developed at the National Solar Observatory (NSO) to provide 12 a near contemporaneous source of data to drive numerical models. Here, we apply these NSO-HMI-13 NRT maps to simulate three Carrington rotations (CRs): 2107-2108 (centered on 2011/03/07 20:12 14 CME event), 2123 (integer CR) and 2218-2219 (centered on 2019/07/2 solar eclipse), which together 15 cover a wide range of activity level for solar cycle 24. We show simulation results, which reproduce 16 both extreme ultraviolet emission (EUV) from the low corona while simultaneously matching in situ 17 observations at 1 au as well as quantify the total unsigned open magnetic flux from these maps. 18
