The results of the sulfur dioxide measurements are shown in Table 7. The time of wetness values were determined from the relative humidity results using the procedure shown in ISO 9223, where wetness is assumed whenever the relative humidity is above 80% and the temperature is above 0°C. The values shown in Table 8 are in hours per year. The chloride deposition rates were determined from the wet candle technique and are shown in Table 9 as mg NaCl /m² day.
