| Resumo | The Total Electron Content (TEC) of the ionosphere can be calculated by parameters observed by GPS receivers located in the ground. As a result of the differential phase and group calculation, the non-dispersive terms are canceled, leaving terms due to biases of the satellites and the receiver together with the ionospheric error contribution to the signal. The slant TEC (STEC) corresponds to an arc of TEC for each satellite measured by a given receiver. The combination of the various STECs observed by a receiver using selected methods and mapping functions results in a vertical TEC (VTEC) over the ground station. In this work, the performance of three different VTEC calculation techniques, each one using their own methods to eliminate biases and to obtain VTEC from STECs, is evaluated to describe the ionosphere conditions in the equatorial and low latitude regions in the Brazilian sector. I order to do this, data from a station in the equatorial region, Sao Luis, and a station in the southern crest of the Equatorial Ionization Anomaly (EIA), Cachoeira Paulista, were used. The study was made for a period of minimum solar activity (November 2008 to October 2009) and one of maximum solar activity (November 2014 to October 2015) and the seasonality of TEC along the year was also studied. The three techniques used are: (I) the technique developed by the University of Nagoya, Japan, and adjusted at the National Institute of Space Research (INPE), Brazil, to be used by the Brazilian Space Weather Program (EMBRACE), (II) a technique developed at Boston College, USA, and (III) the method proposed by the International Centre for Theoretical Physics (ICTP), Italy. The evaluation of the TEC curves obtained showed that all three techniques present results consistent with each other but with some small divergences in certain periods. The three techniques show the significant reduction of the TEC in the period of minimum solar activity and during the winter in any condition of solar activity. All techniques showed an increase in TEC at the station under the crest of the EIA in the summer and during the equinoxes due to the intensification of the fountain effect during the day and the pre-reversion peak at the sunset. The large discrepancies between the results obtained by the three techniques were observed during the beginning of the night hours due to the presence of ionospheric irregularities. The method used in INPE responds well to the daily, seasonal and solar cycle variations of the TEC, presenting, on several occasions, intermediate results with respect to the other techniques in the Brazilian region, showing to be suitable to be used by EMBRACE program to monitoring this region. | |||
