Atmospheric CO2 mole fraction data observed at Yoyogi, Tokyo by AIST

This data set contains CO2 mole fraction data observed on a roof-top tower of Tokai University (52 m above ground) and the vertical difference in the mole fractions between 52 and 37 m in Yoyogi (YYG; 35.66° N, 139.68° E), Tokyo, Japan. The YYG site is a residential area located near the central part of Tokyo. The main landcover around the site is characterized by residential buildings with a mean height of 9 m.本数据集包含两类观测数据：其一为在日本东京东海大学一座离地52米的楼顶观测塔上测得的二氧化碳摩尔分数（CO2 mole fraction）数据；其二为位于日本东京代代木（YYG；北纬35.66°，东经139.68°）的52米与37米高度间的摩尔分数垂直差值数据。代代木观测点地处东京市中心近郊的居民区，站点周边的主要土地覆盖特征为平均高度9米的住宅建筑群。
