                          |  | In this model, the Dst index is predicted 2 hours in advance with one hour time step using the real-time ACE data. The model is described in Influence of solar wind dynamic pressure on the decay and injection of ring current.  |  |  | 
                        
                          | The D region absorption prediction product consists of three components: a global map of HF radio wave absorption due to solar X-ray flux, an attenuation bar graph, and an estimated recovery clock.  |  |  |  |
