NOAA Updates Space Weather scales to Reflect Modern Understanding
Just like hurricanes and tornadoes, space weather storms pose important threats to Earth. These celestial events,though,are far more complex than terrestrial weather phenomena,requiring a specialized classification system. NOAA’s Space Weather Scales, initially developed in 1999, categorize space weather events into three primary types: geomagnetic storms, solar radiation storms, and radio blackouts. Each category is rated on a scale of 1 to 5, indicating the intensity and likelihood of occurrence.
these scales, created as space weather research gained prominence, aimed to provide a standardized framework for understanding and communicating the potential impacts of solar flares. Though,significant events like the Halloween solar storm in October 2003 and the recent Gannon event in May 2024 highlighted the limitations of the existing scales. These historic events underscored the need for updated criteria and a clearer understanding of the evolving nature of space weather.
“The scales were designed in 1999 as space weather started becoming a more popular area of research. But with historic events, including the Halloween solar storm in October 2003 and the Gannon event in May 2024, bringing new information to light, we realized they needed to evolve,” stated Michael Murtagh, Program Led for NOAA’s Space Weather prediction Center. “These events demonstrated the need for greater precision and clarity in categorizing space weather phenomena.”
Recognizing the necessity for enhancement, NOAA embarked on a complete revision process, incorporating insights from scientists, industry experts, and the public. This collaborative approach ensures the updated scales accurately reflect the latest scientific understanding and address practical concerns.
One key focus of the revision is addressing ambiguity and enhancing clarity. The updated scales aim to provide more precise definitions and criteria for each category, minimizing confusion and ensuring consistent interpretation across various stakeholders. Differentiating severe events,particularly those with potentially catastrophic consequences,is another crucial aspect. By establishing clearer thresholds, the revised scales can provide timely warnings and facilitate effective preparedness measures.
NOAA is implementing the updated scales in a phased approach, allowing for ongoing evaluation and refinement. This iterative process ensures the scales remain relevant and effective as our understanding of space weather continues to advance.
Looking ahead, the revised space weather scales represent a significant step towards enhanced preparedness and resilience. these updated tools empower individuals, businesses, and governments to anticipate, mitigate, and respond effectively to the potential impacts of space weather events. Understanding and preparing for space weather is crucial in our increasingly interconnected world, where disruptions to critical infrastructure can have cascading effects.
While the updated scales provide valuable insights, ongoing research and collaboration remain essential. Continuous monitoring, data analysis, and public engagement will further refine our understanding of space weather and ensure the scales remain effective tools for safeguarding our technological infrastructure and societal well-being.
Revamping Space Weather Scales for a Modern Age
The National Oceanic and Atmospheric Administration’s (NOAA) Space weather Prediction Center (SWPC) is set to revamp its space weather scales, ushering in a new era of clarity and precision in communicating the potential impacts of solar activity on our technological infrastructure and daily lives. This initiative, driven by the need for more nuanced and user-kind scales, signifies a critical step forward in our understanding and preparedness for space weather events.
Public Input Drives the Revision Process
The SWPC embarked on this ambitious project by actively soliciting input from a diverse range of stakeholders, including scientists, engineers, policymakers, and the general public. this extensive engagement, which garnered nearly 500 responses from nearly 200 organizations, underscores the collective commitment to improving space weather communication. Daniel Pechkis, a research staff member at the Space Technology and Policy Institute (STPI), stated in an email to Space.com, “STPI will deliver a report to NOAA that will consist of different Space Weather Scales revision options for NOAA to consider. Over the next year, STPI will work with NOAA to evaluate the various options, helping them determine the feasibility and timeline needed for possible implementation. Throughout this process, STPI will continue to work with the space weather community and users of space weather information to inform SWPC’s scales revision effort, delivering a suggested implementation plan near the end of the year.”
Addressing Ambiguity and Enhancing Clarity
One of the key findings from the public feedback was the need to address ambiguity in the existing scale descriptions. Terms such as “minor” and “extreme” can be subjective and lack precision when communicating the potential impacts of space weather events. Murtagh explained, “Such as, on the geomagnetic storm scale, the G5 ‘extreme’ description is going to mean one thing to one person and something totally different to others. It depends on their system,the sophistication of the technology they’re using,and the latitude and location to where they’re at.” The revised scales aim to provide more specific and objective criteria for each level, ensuring a clearer understanding of the potential consequences of space weather events for various systems and sectors.
Differentiating Severe Events
Another area of focus is the differentiation between severe space weather events.For instance, the Gannon event, classified as a G5, demonstrated that even events within the “extreme” category can vary significantly in their impact.The revised scales aim to create subcategories or tiers within each level to better reflect the wide range of potential severity.
staying informed about space weather events is crucial for individuals, businesses, and critical infrastructure operators. By understanding the potential impacts and utilizing the updated NOAA Space Weather scales, we can minimize risks and ensure resilience in the face of celestial disturbances.
Revamping Space Weather scales: An Interview with Michael murtagh
space weather, the dynamic activity on the Sun and its impact on Earth, poses both challenges and opportunities for our technologically reliant world. To effectively communicate the potential risks and consequences of solar storms, the Space Weather Prediction Center (SWPC) is undertaking a significant revision of its space weather scales.
Addressing Saturation Concerns
the existing scales, while valuable, have limitations, particularly at their higher ends.

Murtagh envisions a future where a new scale design emerges. “There’s a different type of scale that would eliminate that concern of the saturation at the high end of the scale,” he said. “That’s a big one and would take some time to create, but we feel like we can make some progress here in the next couple of years.”
A Phased Approach to Implementation
The SWPC is implementing this significant upgrade in a phased approach. Currently in phase two, experts are analyzing public feedback and the STPI’s report to prioritize changes and determine the most efficient implementation strategy.
“The third and final phase will involve ‘making it happen,implementing change,defining and changing the products,and [creating] a subscription service to get to the customers by notifying everybody these changes are coming. And so that’s going to be a lot of time and effort, but obviously it’s critical to do,” explained Murtagh.
Looking Ahead: Enhanced Preparedness for Space Weather
The revitalized space weather scales represent a monumental step towards a more resilient and informed society. By providing clearer, more precise information about the potential impacts of solar activity, these updates will empower individuals, businesses, and governments to better prepare for and mitigate the potential disruptions caused by space weather events.
