Inorganic Constituents in Precipitation in Yonezawa City
Entry ID:
JSYUAR-8
Summary
Abstract:
Since May 1989, the rainfall have been collected at 12 meters above
the ground in Yonezawa City (campus of Faculty of Engineering, Yamagata University - located in southern inland in Yamagata Prefecture). Each ion concentration of sodium, potassium, calcium, magnesium, ammonium, chloride, nitrate, and sulfate, as well as preciptation amount, electric conductivity and pH have been measured for each rainfall or each snowfall. Maximum value, minimum value, mean value, composition ratio and so on are summarized in every each year. By the blow of north west seasonal wind which sprouts from the winter over the early spring, the material which seems to be sea salt from the Sea of Japan and acid deposition from the continent are observed. Measurements are continued at present. Geographic Coverage
