Above-ground plant can be exposed to extreme temperatures, and to humidity that varies with the seasons and with daily temperature changes. When humidity condenses on the surfaces of outdoor apparatus or equipment, the corrosivity of the moisture layer can be increased by industrial pollutants that render the condensate moisture corrosive. In sea coastal areas, wind-borne, salt-laden water droplets can deposit on exposed components.
