Global buffering of temperatures under forest canopies

Accuracy of Kinematic Positioning Using Global Satellite Navigation Systems under Forest Canopies

A harvester enables detailed roundwood data to be collected during harvesting operations by means of the measurement apparatus integrated into its felling head. These data can be used to improve the efficiency of wood procurement and also replace some of the field measurements, and thus provide both less costly and more detailed ground truth for remote sensing based forest inventories. However,...

Biodiversity meets the atmosphere: a global view of forest canopies.

The forest canopy is the functional interface between 90% of Earth's terrestrial biomass and the atmosphere. Multidisciplinary research in the canopy has expanded concepts of global species richness, physiological processes, and the provision of ecosystem services. Trees respond in a species-specific manner to elevated carbon dioxide levels, while climate change threatens plant-animal interacti...

The ecology of tropical rain forest canopies.

With the advent of increasingly sophisticated techniques for access, tropical forest canopy research has burgeoned in the last few years. Although an enormous amount of basic descriptive work remains to be done, canopy research is now entering a more advanced and ecological phase.

Microwave Scattering Model for Nonuniform Forest Canopies

Spectroscopic Remote Sensing of Non-Structural Carbohydrates in Forest Canopies

Non-structural carbohydrates (NSC) are products of photosynthesis, and leaf NSC concentration may be a prognostic indicator of climate-change tolerance in woody plants. However, measurement of leaf NSC is prohibitively labor intensive, especially in tropical forests, where foliage is difficult to access and where NSC concentrations vary enormously by species and across environments. Imaging spe...
