             abstract = "The Embrace Magnetometer Network (Embrace MagNet) uses a series of 
                         magnetometers over South America to monitor the Earths space 
                         environment and to study space weather. One of the common 
                         techniques used to study the effects of the magnetic disturbances 
                         in the globe is through the Quiet Day Curve (QDC) of the 
                         geomagnetic field components. These types of QDC are calculated 
                         based on geomagnetic field data collected by magnetometers in the 
                         5 quietest days for each month at each station. Thus, we developed 
                         and implemented an empirical model based on the QDC H component 
                         obtained by the Embrace MagNet. This model ought to be used as a 
                         prediction device when data is not available. The proposed 
                         algorithm is a function of the solar activity, the day of the 
                         year, and the universal time, which was adjusted based on 12 
                         stations across to the South America sector between 2010 and 2018. 
                         Our results show that the values computed by this model are in 
                         good agreement with the observational data for the QDC. Finally, 
                         it is essential to mention that the QDC model presented in this 
                         study is the only available forecasting tool of the Embrace MagNet 
                         stations to the date, providing data with a high confidence level 
                         in the Brazilian sector.",
