Atmospheric corrosion is a severe challenge for most common metals due to its effect on the service life and strength of structural materials, especially steel structures. In a tropical climate country such as Malaysia, high humidity, temperature, and rainfall precipitation contribute to the high time of wetness in the atmosphere. The wetness condition and air pollution will accelerate corrosion formation. Rapid economic growth and development of industrial areas have significantly increased the number of corrosion agents immerse in the atmosphere. Since corrosion is influenced by the atmosphere, the changes in corrosion level would be identified by comparing the corrosion hazard map for 10�years duration. The climate and air pollution data were analyzed using the inverse distance weighting (IDW) method to form a Corrosion Hazard Map of Peninsular Malaysia. Observation on the maps discovered that throughout the 10�years, southern and west coast areas have the highest corrosion level, while the lowest corrosion level occurred around the center part of Peninsular Malaysia. Information on the corrosion level will benefit highly dynamic industries in planning and decision-making, indirectly reducing losses. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
