Real-time Disturbance-storm-time (Dst) indices forecasted by Machine-Learning (ML) modeling of solar-wind data

Note: The observatory-based Dst (plotted for comparison) are obtained from the World Data Center for Geomagnetism in Kyoto. These "Quicklook" Dst values are unverified, may contain errors, and are subject to change.

Overview

This Google Sheets application provides a convenient way to calculate the Earth's main magnetic field components using the official World Magnetic Model (WMM) 2025. The WMM is a standard model developed by the US National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey (BGS), representing the global magnetic field for a specific five-year epoch.
