巴罗科罗拉多岛（Barro Colorado Island）AVA塔（AVA tower）。设有两组传感器，分别为北向传感器与南向传感器。监测指标为光合有效辐射（Photosynthetically Active Radiation, PAR），记录监测间隔内的最大值、最小值与平均值。

本数据集于2011年3月设立，作为森林地理监测网络（ForestGEO）热带生态评估与监测（Tropical Ecology, Assessment and Monitoring, TEAM）项目的组成部分。初始搭建的塔台位于该岛中心附近、50公顷样地的西北角，坐标为北纬9.1568°，西经79.8486°。2018年，该塔被倒塌的树木撞击，无法继续使用。2019年2月，在原址附近新建了一座高度为45米的新塔，坐标仍为北纬9.1568°，西经79.8486°。
