VTEC

Unit: (10^16 el) / m^2

VTEC, or Vertical TEC, is a specific type of TEC measurement that is taken along a path extending vertically from the Earth's surface to the edge of the atmosphere. Essentially, VTEC is a subset of TEC, with the difference lying in the specific path along which the measurement is taken.
