International Aviation Weather System

Modernizing Aviation Weather Systems Worldwide

RAL has spent the past several decades addressing and supplying the needs of aviation stakeholders in the U.S. and other countries. This work has yielded fundamental improvements in the scientific understanding of aviation weather hazards as well as a broad array of practical tools and systems that reduce the vulnerability of aviation to such hazards.

Current and projected growth in the volume, complexity, and economic importance of air and space transportation clearly demonstrates the need for a new paradigm supporting the organization and control of air traffic services in the 21st century. Since weather conditions seriously impact air traffic operations and the levels of service available to system users, the manner by which weather is observed, forecast, disseminated and used within air traffic decision processes and systems is of critical global importance.

For more than 25 years, RAL has worked with international civil aviation authorities to modernize their aviation weather systems. This work includes developing and implementing wind shear and turbulence alerting systems, four dimensional gridded aviation weather forecasting systems that include guidance products covering in–flight icing, turbulence, winds, temperatures, ceiling and visibility, and convective hazards. RAL's international aviation weather research and development leverages the results of RAL's aviation weather research conducted with Federal Aviation Administration (FAA) and National Aeronautics and Space Administration (NASA) funding. For more information on this research, see the Aviation Applications Program (AAP) page. RAL has worked successfully with civil aviation authorities in several countries including, Taiwan, Singapore, Hong Kong, Korea, Saudi Arabia, Kuwait, Spain, Columbia, and Australia.
