Geomagnetic Disturbance-storm-time (Dst) index is predicted in real-time using a Machine-Learning algorithm, driven by NOAA's Deep Space Climate Observatory (DSCOVR) data. The predicted data are compared against the official Dst data derived from ground geomagnetic observatories. Dst is a measure of the severity of the geomagnetic storm. Dst index is used to drive geomagnetic disturbance models such as NOAA's High Definition Geomagnetic Model - Real-Time. (HDGM-RT) as well as to determine the quality of magnetic survey data. Dst is officially calculated as an average value of the horizontal component of the magnetic field observed at four near-equatorial observatories. This prototype model is not intended to be used in operations. If you notice anything unusual, please send us an email at geomag.models@noaa.gov.
