NASA’s AI-powered forecasts provide advance notice of solar storms, providing critical preparation time to protect power grids and critical infrastructure. By examining the spacecraft’s solar wind data, the AI model can predict the location of future solar storms with a lead time of 30 minutes.
A solar storm is a violent disturbance caused by a sudden release of energy from the Sun. These storms have a significant impact on Earth’s space environment, disrupting satellite communications, power grids, and navigation systems.
Today, NASA is harnessing the power of artificial intelligence (AI) to improve our understanding and prediction of solar storms.
Understanding Solar Storms and Their Effects
The Sun is constantly emitting solar material, including steady streams known as the “solar wind” and more powerful explosions during solar eruptions. When this material interacts with the Earth’s magnetic environment, known as the ‘magnetosphere’, it can cause geomagnetic storms. These storms vary in strength and can disrupt our technology-dependent world.
Multinational experts, including NASA, the U.S. Geological Survey, and the U.S. Department of Energy, are collaborating to use artificial intelligence to identify links between the solar wind and destructive geomagnetic disturbances. The researchers hope to better prepare for such disruptions by employing a technique known as deep learning, which teaches computers to recognize patterns using past examples.
DAGGER: A Revolutionary AI Prediction Model
The team developed a computer model called DAGGER (Deep Learning Geomagnetic Perturbation) that accurately predicts geomagnetic storms around the world 30 minutes in advance. The model generates predictions within seconds and updates every minute. Tests performed on the model using geomagnetic storms in August 2011 and March 2015 demonstrated DAGGER’s accurate prediction of global storm impacts.
DAGGER is a breakthrough forecasting model that combines AI with real-time space and earth measurements to provide timely and accurate geomagnetism predictions worldwide. The computer code for this model is available as open source and can be customized to meet specific requirements by grid operators, satellite controllers, telecommunications companies, and others.
Using these forecasts, stakeholders can receive advance warning of solar storms and take necessary actions to protect their assets and infrastructure. These measures may include temporarily shutting down sensitive systems or repositioning satellites to minimize potential damage.
Models like DAGGER may one day allow solar storm sirens to be installed in power plants and satellite control centers around the world. Similar to tornado sirens that warn of approaching severe weather, these solar storm sirens act as a warning system for potential solar storms approaching Earth.
