A physics-based model of the ionosphere and electric fields is used to discern the neutral wind drivers of the low latitude ionosphere in the South American region. The data assimilated are from the collaborative data sources for the Low Latitude Ionospheric Sensor Network. These data include vertical TEC from GPS monitors, magnetic field variations from magnetometers, and F2 critical frequencies from ionosondes. These instruments are spread out across the South American continent. We will present results of the longitudinal variations of the E and F region neutral wind drivers and the resulting dynamo electric fields. Solar and Lunar tides are necessary inclusions in the dynamo physics. Thus, the data ingestion must be approached though examination of different time scales within the data for the appropriate separation of drivers.
