Summary Precipitation, pH, SO4 and CL from rainfall were collected during one month. They were measured by the English standard deposit gauge at 10-odd points in Kagoshima City since 1987. Measurments were also taken in Kagoshima City and in the Sakurajima area from 1978 to 1986.
SOx in the atmosphere (average value for one month) and NOx (24hr) were both measured by the SOx adsorption method (1978-1986). The NOx badge method has also been used since 1987. Geographic Coverage
