We explore model performance for the Alfven Wave Solar atmosphere Model(AWSoM) with near-real-time (NRT) synoptic maps of the photospheric vectormagnetic field. These maps, produced by assimilating data from the HelioseismicMagnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO), use adifferent method developed at the National Solar Observatory (NSO) to provide anear contemporaneous source of data to drive numerical models. Here, we applythese 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 ofactivity level for solar cycle 24. We show simulation results, which reproduceboth extreme ultraviolet emission (EUV) from the low corona whilesimultaneously matching in situ observations at 1 au as well as quantify thetotal unsigned open magnetic flux from these maps.
