An empirical regional TEC model response to external forcing (geomagnetic and day-to-day solar variability) is built (for details see the PDF file). This model, covering the Balkan Peninsula (35-50ºN; 15-30ºE), is constructed by using the CODE TEC data for the period of 1999-2015 and offers hourly maps of the TEC for the current and next day (i.e. for 48 hours).
