                         at 777.4 nm and 630.0 nm have been used in the past few years to 
                         determine the ionospheric F-layer peak electron density and peak 
                         height, and to investigate the pattern of F-layer depleted plasma 
                         regions, or ionospheric transequatorial plasma bubbles, and their 
                         associated irregularities in the tropical ionosphere. Meridional 
                         scanning observations of these emissions at low latitudes, made 
                         with groundbased filter photometers, are presented in the form of 
                         computer generated three-dimensional perspective views, showing 
                         the spatial north-south and temporal intensity variatons of these 
                         OI emissions, for both normal conditions and in the presence of 
                         magnetic field-aligned large scale plasma irregularities or 
                         bubbles. The significant features of these observations are 
                         discussed. This remote sensing airglow technique shows to be very 
                         useful to study ionospheric plasma dynamical processes and to 
                         investigate the pattern and time evolution of large scale plasma 
                         irregularities in the nightime tropical ionosphere.",
