             abstract = "This paper presents a study of diurnal tidal winds observed 
                         simultaneously by two meteor radars located on each side of the 
                         Equator in the equatorial region. The radars were located in Santa 
                         Cruz, Costa Rica (10.3 degrees N, 85.6 degrees W) (hereafter CR) 
                         and Sao Joao do Cariri, Brazil (7.4 degrees S, 36.5 degrees W) 
                         (hereafter CA). The distance between the sites is 5800 km. 
                         Harmonic analysis has been used to obtain amplitudes and phases 
                         (hour of peak amplitude) for diurnal, semidiurnal and terdiurnal 
                         tides between 82 and 98 km altitude, but in this work we 
                         concentrate on the diurnal component. The period of observation 
                         was from April 2005 to January 2006. The results were compared to 
                         the Global Scale Waves Model (GSWM-09). Magnitudes of zonal and 
                         meridional amplitudes from November to January for CR were quite 
                         different from the predictions of the model. Concerning phases, 
                         the agreement between model and radar meridional tidal phases at 
                         each site was good, and a vertical wavelength of 24 km for the 
                         diurnal tide was observed practically every month, although on 
                         some occasions determination of the vertical wavelength was 
                         difficult, especially for the zonal component, due to nonlinear 
                         phase variations with height. For the diurnal zonal amplitude, 
                         there were notable differences between the two sites. We attribute 
                         this site-to-site difference of the diurnal zonal amplitude to the 
                         nonmigrating component of the tide and propose that an anomaly was 
                         present in the troposphere in the winter (Northern Hemisphere) of 
                         2005-2006 which produced substantial longitudinal variation.",
