TEC 30-day Climatology
Please Note:We are aware of issues with the TEC maps on this page. These plots are not functioning correctly. A fix is currently being investigated.

Displayed here is a dynamically updated recent climatology TEC map produced at ASWFC from the previous 30 days of observations.
The map is produced by gridding the TEC map and determining the median value at the given time of day over the last 30 days. This produces a baseline recent climatology that automatically adjusts for the seasonal and solar cycle differences in the undisturbed ionosphere. By comparing this with the currently observed conditions, we derive the disturbance map.
The map shows colour contours of TEC in units of 1016 electrons/m2 (=TECU).
