Yearly Reports_San Lorenzo Crane

Yearly climate summaries for the Smithsonian Tropical Research Institute's Physical Monitoring Program Sherman/San Lorenzo (FTS) Canopy Access Crane Station. Established in 1997, the San Lorenzo canopy crane (9.281031°, -79.974518°) is located approximately 11 km South West from the city of Colon, in the middle the Parque Natural San Lorenzo (formerly known as Fort Sherman) and is surrounded by 300-year old, low-land tropical rainforest.

The crane stands in a 6-hectare plot where all 22,400 trees with a bole size of 1 cm in dbh or greater have been identified, measured and mapped. Structurally, the forest can be characterized as including 3,338 stems per hectare (greater than 1 cm dbh) and a total basal area of almost 32 m2 per hectare with the tallest trees being 45 m tall. The base of the crane is approximately 175 mmsl

本数据集为史密森热带研究所（Smithsonian Tropical Research Institute）物理监测项目下设的谢尔曼/圣洛伦佐（FTS）冠层接入起重机站点的年度气候汇总数据。圣洛伦佐冠层起重机建于1997年，坐标为9.281031°、-79.974518°，坐落于科隆市西南约11公里处的圣洛伦佐自然公园（原名为谢尔曼堡）的中心区域，周边环绕着300年树龄的低地热带雨林。该起重机坐落于一片6公顷的监测样地中，样地内所有胸径（diameter at breast height, DBH）≥1厘米的22400株树木均已完成识别、测量与绘图建档。从林分结构特征来看，该区域每公顷胸径≥1厘米的植株数量达3338株，总断面积约32平方米/公顷，最高树木高度可达45米。该起重机基座海拔约175 mmsl。
