– Navigation and communication
– Airline safety:
– Navigation and communication
– Radiation
Increasing Vulnerabilities to Space Weather
• 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
Addressing Space Weather through International Cooperation
• 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 is Driven by Atmospheric Disturbances from Below and Solar Disturbances from Above
Transformer damage
Failures of GPS based positioning
Polar flights rerouted
NOTAMAirline communication impacts
Oilfield services instrument Interference
SatComm and HF outages
Nuclear power plants reduced power
Widespread HF outage over African continent
SatComm and HF outages
Over 130 hours of HF communication blackout in Anarctic
Japan’s Data Relay Test Satellite safe mode
Space Weather Impacts are Global
Reported impacts from a storm in October, 2003
Strong Customer Growth is Occurring During Quiet Solar Conditions
Air Canada Air China Air New Zealand American Airlines British Airways
Cathay Pacific Airway Korean Air Lufthansa Quantas Airways United Airlines
Examples of global airline customers:
Customer Demand for Space Weather Products in U.S.
2011 March 7 20 UTC
2011 March 8 10:48 UTC
Global Products are Available for HF Radio Communication
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
Ionospheric Disturbances Occur at All Latitudes
Kintner et al., 2009
Ionospheric disturbances create Global Navigation Satellite System (GNSS) position errors and loss of signal.
Disturbances can last from hours to days.
Frequent
Infrequent
Scintillation Occurrence Frequency
Highest occurrence frequency is at low and high latitudes. During large storms, disturbances extend into mid latitudes.
Expanding GNSS Applications
- Airline navigation systems - Agriculture- Mining operations - Deep-sea drilling- Surveying - Construction
GNSS will continue to increase in importance to all Members
Global Navigation Satellite Service (GNSS) Applications are Growing Rapidly
New Initiative Within the U.S. National Space Weather 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
Integrated Space Weather Science and Service Program
Educational Resources for Space Weather
- 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
