ZAMSECUR Project Miombo Forest, Zambia, Southern Africa

The Observation tower was set up in a dense Miombo Forest in Mpika, Zambia in Southern Africa. The Bowen ratio (BR) is estimated using the Distributed Temperature Sensing (DTS) system. The daily BR is an average of hourly estimates. The DTS approach for estimating the Bowen ratio in a forest is explained in Schilperoort et al (2018). The Silxa XT DTS machine was used. The Net radiation above forest canopy (11 m above ground) was collected at site using NR Lite 2 net radiometer, relative humidity, air temperature were collected at 2 m above ground at the site. soil moisture was collectedin the subsurface at 30 cm. The wind speed was collected above the forest canopy at 16.5 m above the ground.

观测塔设立于南部非洲赞比亚姆皮卡地区一处茂密的米奥姆博林（Miombo Forest）中。本研究采用分布式温度传感（Distributed Temperature Sensing, DTS）系统估算波文比（Bowen ratio, BR），日均波文比为逐小时估算值的平均值。森林生态系统波文比的DTS估算方法已由Schilperoort等人于2018年的研究中详细阐释。本次实验使用Silxa XT型DTS设备开展观测。站点同步采集了多组环境观测数据：林冠上方（距地面11米）的净辐射数据由NR Lite2型净辐射计（NR Lite 2 net radiometer）获取；距地面2米高度处采集相对湿度与空气温度数据；地下30厘米土层中采集土壤含水率数据；林冠上方距地面16.5米处采集风速数据。
