Many summary statistics are used to construct area-based regression relationships, but one has proven particularly effective for modeling carbon from ALS: the top-of-the-canopy height, TCH, defined as the average height of the uppermost returns measured in the pixels comprising a plot (Asner and Mascaro 2014).
The uppermost part is defined as the mainstream between the headwaters on the Tibetan Plateau and Yibin, the latter being located at the river's entrance to the Sichuan Basin.
Ten days after pollen shed, five consecutive plants from the middle of each plot were chosen to evaluate the ILAU (ILFir, ILSec, ILThi, ILFor, and ILFif, the first, second, third, fourth, and fifth internode length above the uppermost ear, respectively), and each internode length was defined as the length from node to node.
Total length of the tibia (TLT) was defined as the length of the tibia, and was measured on standing lower-extremity anterior-posterior radiographs parallel to the long axis from the uppermost portion of the tibial eminence to the midpoint of the lowermost portion of the tibial plafond (L1 and L2).
The confinement aperture, which is required for better carrier and light confinement, was defined in the uppermost layer of the bottom DBR.
This layer forms the uppermost part of unit 2 and is defined as subunit 2A.
The historic region was defined as Classico.
When the uppermost internode showed twining extension, the growth habit characteristic was recorded as '1'; when the uppermost internode was non-twining it was recorded as '0'.
In the tropics, by contrast, species-diverse forests that can be described as stunted evergreen rainforests typically grow as far as the uppermost limits of tree growth.
