IPS : T Index Map
This image shows the DIFFERENCE between current OBSERVED HOURLY conditions and PREDICTED MONTHLY conditions for the Australian region. 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.

HAP charts are designed for communications between a specified base and mobile within a nominated area.
The HAP chart is a guide to frequency selection for HF communications between mobiles and a specified base station, in this case Brisbane. The recommended frequency for communications with the base at a given hour is read off from the point in the map corresponding to the mobile's location.The predictions are made from real time data which are updated each hour.
'dash lines' - If present, these delineate areas of unlikely communication. Poor communication areas which can result from one or more of the following conditions:
- the Absorption Limiting Frequency (ALF) is higher than the Optimum Working Frequency (OWF).
- the ALF exceeds the highest frequency in the user's frequency set.
- there is no suitable frequency from the user's set that is between the OWF and ALF.

The real-time ionospheric total electron content data below updates every 60 minutes so you will need to press your browser's Refresh function occasionally to ensure that you have the latest image.....
This near real-time ionospheric total electron content (TEC) world map is produced at IPS by using the IRI-90 ionospheric model with real-time foF2 data obtained from the region. You can compare this derived product with the NASA JPL Global TEC Map. Note that the IPS dervied map may lag the NASA JPL map by an hour and is centred on a different longitude.
