Dataset Information

Site ID: BR-Ma2

Site Name: Manaus - ZF2 K34

Variables: Leaf gas exchange

Date Range: Feb. 15, 2015 - March 16, 2017

Description: Raw leaf gas exchange data from K34 tower site on a plateau near Manaus, Brazil, collected using sensor and leaf sample measurements. Leaves on a target tree were chosen by accessing a branch near the tower. In some cases, the branch was naturally positioned near the tower and in other cases, a small rope was used to pull the branch closer to the tower for better access to leaves. Mature leaves were targeted in nearly all cases. The gas exchange system was hauled with a climbing rope to the level of the branch on the tower and the sensor head/leaf enclosure was installed near the branch of interest using a magic arm. We measured leaf gas exchange from 5:00 AM to 5:00 PM, randomly cycling through the approximately 20 leaves in the targeted branch(es). Data was collected over two time periods, detailed within the files. Attached data files contain raw data, sensor manuals, and PDFs with detailed methods and procedures. See data references for data package containing related metadata. This dataset replaces the leaf gas exchange data of two retired packages, http://dx.doi.org/10.15486/ngt/1507764 and http://dx.doi.org/10.15486/ngt/1507767
