Atmospheric Impurities in the City of Maebasi

[摘要] In this paper, the author studied the atmospheric impurities in the City of Maebasi observed during July 19th-July 30th, 1941.As for the method of determination of the atmospheric impurities is referred to this Journal II 17 (1941), p. 367.The results obtained are as follows:-1. The chloride content diminishes remarkably with increasing wind velocity.2. There is a negative correlation between the chloride content and the humidity of the atmosphere, as in the case of W. C. Jacobs.3. A trace of the sulphuric acid content is noticed.4. There is a parallelism between the daily variation of the amount of ammonia and the temperature at the earth-surface.5. The nitrite content in Maebasi is very small compared with that in Tokyo.6. The nitrite decreases the transparency of the atmosphere.
