Global Space Weather Coordination: Perspectives and Activities Dr. Jack Hayes, U.S. Permanent Representative to the WMO, Assistant Administrator for Weather Services and Director, National Weather Service
Outline • Our Increasing Vulnerability to Space Weather • The Need for Global Coordination • Global Space Weather Hazards • Available Training and Services • The Role of the WMO
Increasing Vulnerabilities to Space Weather • HF communication – wireless technology • Electric power grids • Satellite-based applications: • GEO NetCast • Meteorology observations • Navigation and communication • Airline safety: • Navigation and communication • Radiation
Addressing Space Weather through International Cooperation • Operating in space is now an integral component of our economic and security infrastructures • The impacts are global, affecting all regions • Detecting and predicting space weather threats is a complex challenge – impossible for one nation or agency to address alone
Space Weather is Driven by Atmospheric Disturbances from Below and Solar Disturbances from Above • Coordinated ground-based and space-based data and modeling are required over the Sun-Earth system • WMO has an opportunity to coordinate action to address a growing environmental vulnerability.
Space Weather Impacts are Global Reported impacts from a storm in October, 2003 Polar flights rerouted Failures of GPS based positioning NOTAM Airline communication impacts Japan’s Data Relay Test Satellite safe mode Nuclear power plants reduced power SatComm and HF outages Widespread HF outage over African continent Oilfield services instrument Interference Transformer damage SatComm and HF outages Over 130 hours of HF communication blackout in Anarctic
Strong Customer Growth is Occurring During Quiet Solar Conditions Customer Demand for Space Weather Products in U.S. Examples of global airline customers:
Global Products are Available for HF Radio Communication 2011 March 7 20 UTC X-Ray Flares create HF radio communication outages over the daylight region Energetic Particles create HF Radio communication outages and increased radiation at high latitudes HF Communication is critical for: - Commercial Airlines - Humanitarian Operations - Numerous other applications 2011 March 8 10:48 UTC
Ionospheric Disturbances Occur at All Latitudes Ionospheric disturbances create Global Navigation Satellite System (GNSS) position errors and loss of signal. Disturbances can last from hours to days. Scintillation Occurrence Frequency Frequent Infrequent Kintner et al., 2009 Highest occurrence frequency is at low and high latitudes. During large storms, disturbances extend into mid latitudes.
Global Navigation Satellite Service (GNSS) Applications are Growing Rapidly • Expanding GNSS Applications • - Airline navigation systems • - Agriculture • - Mining operations • - Deep-sea drilling • - Surveying • - Construction • GNSS will continue to increase in importance to all Members
New Initiative Within the U.S. National Space Weather Program Integrated Space Weather Science and Service Program - Coordinate interagency activities - Develop the needed science - Integrate new capabilities into operations - Jump start near-term efforts to prepare for Solar Maximum - Establish the partnerships for long-term improvements
Educational Resources for Space Weather http://www.meted.ucar.edu - Background information on space weather and its impacts is available - Additional training resources are planned for development - All Members can utilize this free information online - All Members can obtain services from existing service providers, such as www.spaceweather.gov and www.ises-spaceweather.org Online Space Weather Module
The WMO’s Role - Partner with International Space Environment Service and other relevant entities to optimize capabilities - Solicit WMO Members who can contribute data products and expertise - Coordinate training and services within WMO to benefit all Members - Develop strategy and roadmap to grow capabilities needed to address space weather vulnerabilities proactively THE POTENTIAL ROLE OF WMO IN SPACE WEATHER A REPORT ON THE POTENTIAL SCOPE, COST AND BENEFIT OF A WMO ACTIVITY IN SUPPORT OF INTERNATIONAL COORDINATION OF SPACE WEATHER SERVICES, PREPARED FOR THE SIXTIETH EXECUTIVE COUNCIL April 2008
