Additional information

This test site was included in the National Corrosion Map elaborated in the early 90’s. Chloride and SO2 deposition rates were measured by the wet candle method and by the sulphur dioxide method, respectively (ISO 9225). Climatic data from the nearest weather station owned by the Portuguese Institute for Sea and Atmosphere (IPMA) at the time, 8 km distant, also on the shore. It is currently active, measuring data on air temperature, atmospheric pressure, relative humidity, solar irradiance, rainfall, wind speed and direction, which is available on request.
