The long.tudinal dependence of the behavior of ionospheric parameters has been the subject of a number of works where sig.ificant variations are discovered. This also applies to the prediction of the ionospheric total electron content(TEC), which neural network methods have recently been widely ***, the results are mainly presented for a limited set of meridians. This paper examines the long.tudinal dependence of the TEC forecast accuracy in the equatorial zone. In this case, the methods are used that provided the best accuracy on three meridians: European(30°E), Southeastern(110°E) and American(75°W). Results for the stations considered are analyzed as a function of long.tude using.the Jet Propulsion Laboratory g.obal Ionosphere Map(JPL g.M) for 2015. These results are for 2 h ahead and 24 h ahead forecast. It was found that in this case, based on the metric values, three g.oups of architectures can be disting.ished. The first g.oup included long.short-term memory(LSTM), g.ted recurrent unit(g.U), and temporal convolutional networks(TCN) models as a part of unidirectional deep learning.models; the second g.oup is based on the recurrent models from the first g.oup, which were supplemented with a bidirectional alg.rithm, increasing.the TEC forecasting.accuracy by 2-3 times. The third g.oup, which includes the bidirectional TCN architecture(BiTCN), provided the hig.est accuracy. For this architecture, according.to data obtained for 9 equatorial stations, practical independence of the TEC prediction accuracy from long.tude was observed under the following.metrics(Mean Absolute Error MAE, Root Mean Square Error RMSE, Mean Absolute Percentag. Error MAPE): MAE(2 h) is 0.2 TECU approximately; MAE(24 h) is 0.4 TECU approximately; RMSE(2 h) is less than 0.5 TECU except Niue station(RMSE(2 h) is 1 TECU approximately); RMSE(24 h) is in the rang. of 1.0-1.7 TECU; MAPE(2 h) < 1% except Darwin station, MAPE(24 h) < 2%. This result was confirmed by data from additional 5
