汇聚和共享通量观测点的元数据导致了不同研究领域之间的强有力的合作。这种数据共享也将是未来亚洲塔流量观测网设计的一部分。本综述的目的是了解亚洲塔流量观测点的状况。亚洲共有109个塔流观测点，其中包括51个森林观测点。亚洲在建的新工地比美国和欧洲还多。这些地点的范围从西伯利亚的泰加到东南亚的热带雨林，从赤道到极地的Koeppen气候带。亚洲有许多高湿润的地区，不仅在低纬度，在中纬度也是如此。这种气候条件形成了独特的植被，如常绿阔叶林，分布在生长季节降水量较大的温暖地区。然而，在绿叶植物森林中只有很少的观察到。稻田也是亚洲独一无二的土地覆盖。积累稻田的长期数据及其管理记录非常重要，因为植物活动在很大程度上取决于气候条件和土地利用管理。通量数据，特别是净生态系统交换和相关要素，不仅用于通量研究界的广泛研究，而且也用于其他研究领域，例如遥感。然而，目前数据的数量和质量都不足以进行这些研究。关于数量，有许多新近建立的站点尚未公布数据；关于质量，通量数据包括由方法问题引起的不确定性。通量研究人员不仅需要获得通量数据，而且还需要提高其质量。同时，数据用户必须明白，通量数据中仍然存在不确定性。
Aggregating and sharing the metadata of flux observation sites results in a strong collaboration among various fields of study. Such data sharing will also be a part of the future design of a tower flux observation network in Asia. The aim of this review is to comprehend the state of tower flux observation sites in Asia. There are 109 tower flux observation sites in Asia including 51 forest sites. There are more new sites under construction in Asia than in America and Europe. These sites range from the taiga in Siberia to the rainforest in Southeast Asia, and from the equatorial to polar Koeppen climate zones. There are many highly humid areas in Asia, not only at low latitudes but also at middle latitudes. This climate condition has developed unique vegetation such as lucidophyllous (evergreen broadleaf) forest, which is distributed in warm areas with high precipitation in the growing season. However, there are only a few observations taking place in lucidophyllous forest. Rice paddy fields are also unique land cover in Asia. It is important to accumulate long-term data for rice fields with their management records, because plant activity depends highly on both climate conditions and land-use management. Flux data, especially net ecosystem exchange and related elements, are used for widespread studies not only within the flux-research community but also in other fields of study, for example remote sensing. At present, however, both the quantity and quality of the data are not sufficient for these studies. Regarding the quantity, there are many recently established sites that have not published data yet; regarding quality, flux data include uncertainties caused by methodological problems. Flux researchers are required not only to obtain flux data but also to improve their quality. Meanwhile, data users must understand there are still uncertainties in flux data.
