Monitor Earth's cosmic ray environment in real-time. Predict geomagnetic storms 1-2 hours before they hit.
Data refreshed from 8 NMDB neutron monitor stations worldwide. Updated every 5 minutes.
Cosmic rays from deep space collide with Earth's atmosphere, producing cascades of muons that penetrate everything around us. Their flux is modulated by solar activity, geomagnetic storms, and atmospheric conditions -- creating an invisible weather system.
Forbush decreases precede geomagnetically induced currents (GICs) that damage transformers. Early warning saves millions.
Cosmic ray flux spikes cause single-event upsets in satellite electronics. Forecast exposure windows for constellation operators.
Aircrew radiation dose varies 2-5x during solar particle events. Real-time muon weather enables dynamic route planning.
Ionospheric disturbances from cosmic ray variations degrade GPS accuracy and disrupt HF communications. Track the cause, not just the effect.
Muon weather connects solar physics to solid Earth geophysics through a measurable causal chain.
Real-time data from the Neutron Monitor Database, spanning polar to equatorial rigidity cutoffs.
Five REST endpoints for muon weather data. Health and demo endpoints are free, no authentication required.
Muon Weather endpoints are included in the DeepMap AI Pro subscription alongside 2,700+ other geophysical endpoints.
