A plot of TEC from the Real Time Run of CTIPe.
Height integrated electron density (TECU, 1 TECU = 1.e16 elecrons/square meter) also called Vertical Total Electron Content (VTEC) vs latitude (-90 to 90 deg) and longitude (0 - 360 deg).
All the TEC gradients summed together.
The TEC temporal gradient.
The TEC longitudinal gradient.
The TEC latitudinal gradient.
