Sampling was carried out monthly from December 1996 to May 1997 and twice a month from June 1997 to December 1999, at eight altitudes from 0.5 km to 7 km. The CO2 concentration in these samples shows clear seasonal variation and secular increase. In the seasonal variations, larger amplitude and earlier phase were observed at lower altitudes. Annual average of CO2 concentration is higher at lower altitudes, suggesting that the ground surface around the observed area act as a source of atmospheric CO2. Extremely high CO2 concentrations accompanied by high concentrations of CH4, N20, CO and H2 were observed several times at lower altitudes, implying that anthropogenic air from the Tokyo metropolitan area often reaches to Sagami-Bay.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
