The results presented here are based on the models described in Hernández-Pajares M., J.M. Juan and J. Sanz, High-resolution TEC monitoring method using permanent ground GPS receivers, Geophys. Res. Lett., 24, 1643-1646, 1997 (direct estimations of TEC variations) and in Juan J.M., A. Rius, M. Hernández-Pajares, J. Sanz, A two-layer model of the ionosphere using Global Positioning System data. Geophys. Res. Lett., 24, 393-396, 1997. Other recent paper about neural network models for the ionospheric electronic content estimation with GPS is Hernández-Pajares M., J.M. Juan and J. Sanz, Neural network modeling of the ionospheric electron content at global scale using GPS data, Radio Sci., 32, 1081-1090, 1997

 
• Coarse tomographic model for the electron content estimation at global scale with GPS during the ionospheric storm in January 10, 1997
• Simultaneous view of the TEC difference of the day January 10th regarding on January 9th 1997, in function on the time (UT of day 97Jan10) for a subset of IGS stations
• TEC(97Jan10)-TEC(97Jan09) in 10/1.05 TECU units, in function of the time (UT of day 97Jan10) for many IGS stations (139 in alphabetic order)
• TEC variation movie of all the data in an inertial reference frame: axis X right ascension, axis Y declination (each 30 minutes; areas not sounded by GPS rays are in black)
