1. The meteorological conditions during the Fukushima Daiichi nuclear power plant accident (mean sea level pressure, wind speed and wind direction) in East Asia. 2. Mean airborne concentrations of I-131 and Cs-137 in the 0-2000 m (planetary boundary) and 2000-10000 m (troposphere) layers.1. 东亚地区福岛第一核电站事故（Fukushima Daiichi nuclear power plant accident）期间的气象条件，包含平均海平面气压、风速与风向。2. 0-2000米（行星边界层，planetary boundary）与2000-10000米（对流层，troposphere）分层内碘-131（I-131）和铯-137（Cs-137）的空气平均浓度。
