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.

The WMM2025 Google spreadsheet enables users to calculate declination values for multiple points. Users can upload a file containing location, altitude, and date information to this spreadsheet. All that's needed is a Google account and a browser to use this application, which is compatible with any operating system. There's no need to install any extensions, and the technique functions effectively in both the web and mobile versions of Google Drive. The multithreaded processing of spreadsheet calculations is remarkably fast.
