The number of outdoor normalized facilities for testing materials worldwide continues to grow as well as the releases of new equipment for atmospheric contamination and materials corrosion assessment. This has a strong impact in many developments of new materials such as those for search, detection, and monitoring of environmental contaminants. Other fields of human activity are also concerned by the present and future atmospheric global changes, especially as regards health and governmental regulations.

This special issue will be mainly focused on new and comparison with previous results from outdoor testing infrastructure observing a wide variety of materials deterioration. Atmospheric corrosion to be considered will be limited to human interaction mainly through the global climatic change and air contamination. This special issue will become an international forum for researchers to summarize the most recent goals and ideas in the field, with special emphasis given to the technical consequences from experimental results obtained within the last ten years. The topics to be covered include, but are not limited to:

• National, regional, and global outdoor testing networks
• Atmospheric corrosion in past and present environmental conditions
• Corrosion susceptibility follow-up with time in overimposed changing situations due to materials development as well as to meteorological and air pollution-related changes
• New technology in paintings and other materials in increasingly aggressive atmospheres
• New technologies designing materials for increasing atmospheric corrosion resistance
• Cultural heritage risks and prevention according to regional and national atmospheric conditions
• Would material improvements balance the increase in atmospheric aggressiveness-related risks?
• Impact of air pollution control programs on material atmospheric corrosion
