                         (dh(f)/dt) can be used to estimate the vertical plasma velocity of 
                         the F layer. This apparent velocity has contributions from the 
                         electromagnetic ExB drift, from the meridional neutral wind and 
                         from the height variations due to recombination, but close to the 
                         magnetic equator and near sunset, when the F layer is high enough 
                         for the recombination process to be considered negligible, the 
                         electromagnetic ExB becomes the most important component. This 
                         paper will present the temporal variations of the vertical drift 
                         approximated with the above technique and also the vertical plasma 
                         velocity derived using a new technique based on the numerical 
                         solution of the continuity equation, both obtained for the 
                         quietest days from the COPEX campaign (October to December of 
                         2002, high solar activity) near sunset hours. We will compare the 
                         vertical ExB drift simultaneously in two magnetically conjugated 
                         stations and at a magnetic equator station, and analyze the 
                         differences and their possible causes in terms of meridional 
                         winds.",
