Global HF

T Index Map

This image shows the DIFFERENCE between current OBSERVED HOURLY conditions and PREDICTED MONTHLY conditions for the global ionosphere. The colours blue, green, yellow, red, correspond to "enhanced", "normal", "mildly depressed" and "depressed" conditions respectively. Depressions and enhancements are with respect to the IPS predicted monthly T index for that month.
