D Region Absorption Predictions (D-RAP)



AIA 131

Information:: Conditions in the D region of the ionosphere have a dramatic effect on high frequency (HF 3-30 MHz) communications and low frequency (LF 30-300 KHz) navigation systems. The global D Region Absorption Predictions (D-RAP) depicts the D region at high latitudes where it is driven by particles as well as low latitudes, where photons cause the prompt changes. The D-Layer map above is synced with the GOES-16 X-Ray flux data also shown above. During solar flare events, the D-Region will experience brief to long lasting radio blackouts on the sunlit side of Earth.
