متن کاملLeaf area index measurements
Leaf area index (LAI) is a key structural characteristic of forest ecosystems because of the role of green leaves in controlling many biological and physical processes in plant canopies. Accurate LA1 estimates are required in studies of ecophysiology, atmosphere-ecosystem interactions, and global change. The objective of this paper is to evaluate LA1 values obtained by several research teams us...
متن کاملEstimation of Leaf Area Index in Dwarf Mountain Pine (pinus Mugo Turra) Using Hyperspectral Data
The natural environment of the Tatras is one of the most diverse in Europe in terms of species richness and ecological value. This mountain range is well preserved and constitutes an important part of Europe’s nature resources. Dwarf pine (Pinus mugo Turra) is the main component of the Tatras subalpine belt covering altitude between 1550 and 1800 m a.s.l. It is a very dynamic species, which exp...
متن کاملRemote Sensing of Mountain Birch Forest Biomass and Leaf Area Index Using ASTER Data
Suitability of ASTER satellite data for estimating biomass and LAI for mountain birch forests was investigated. The field data consisted of 124 plots surveyed in northernmost Finland in July 2004. The statistical relationships between the field measurements and ASTER reflectances were modelled using canonical correlation analysis (CCA) and reduced major axis (RMA) regression. The models were ap...
متن کاملLeaf Area Index in Earth System Models
The amount of leaves in a plant canopy (measured as leaf area index, LAI) modulates key land–atmosphere interactions, including the exchange of energy, moisture, carbon dioxide (CO 2), and other trace gases, and is therefore an essential variable in predicting terrestrial carbon, water, and energy fluxes. The latest generation of Earth system 5 models (ESMs) simulate LAI, as well as provide pro...
