Effect of leaf-on and leaf-off canopy conditions on forest height retrieval and modelling with ICESat-2 data

open access: yesInternational Journal of Digital Earth, 2023
Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) provides effective photon-counting light detection and ranging (LiDAR) data for estimating forest height across extensive geographical areas.

Effects of forest canopy structural complexity on productivity and its stability in the Qinling Mountains: Insights into environmental dependence

open access: yesTrees, Forests and People
Forest canopy structural complexity is a key determinant of forest productivity and exerts a strong influence on its stability. Yet, the relationship between forest canopy structural complexity and productivity and its stability under changing ...

Light intensity affects spatial distribution of Heteroptera in deciduous forests

open access: yesEuropean Journal of Entomology, 2009
Studies on the effect of varying light intensity on the spatial distribution of flying insect communities are rare, particularly in complex ecosystems like forests.

Simultaneous HONO measurements in and above a forest canopy: influence of turbulent exchange on mixing ratio differences [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
We have combined chemical and micrometeorological measurements to investigate the formation and distribution of HONO throughout a forest canopy. HONO was measured simultaneously at two heights, close to the forest floor and just above canopy.

Characterizing spatiotemporal variations of forest canopy gaps using aerial laser scanning data

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Spatiotemporal variations of forest canopy gaps are essential indicators for both forest dynamic monitoring by capturing their size and location variations and forest ecosystem management for tree seedling regeneration through altering the radiation ...

Effect of stand density, canopy leaf area index and growth variables on Dendrocalamus brandisii (Munro) Kurz litter production at Simao District of Yunnan Province, southwestern China

open access: yesGlobal Ecology and Conservation, 2020
Litterfall is the primary interface between the forest canopy and forest floor for efficient carbon and nutrient cycling. However, there is limited knowledge on factors that influence D. brandisii litter production and its seasonal dynamics.

Uncertainty analysis for forest height inversion using L / P band PolInSAR datasets and RVoG model over kryclan forest site

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Forest height, as a measure of the quantity and quality of forest resources, plays a significant role in the study of the ecological functions performed by forests.

Extra Climate Benefits From Afforestation Due to Reduced Forest Fragmentation in China

open access: yesAdvanced Science, EarlyView.
Afforestation in China reduced forest fragmentation in 2015, transforming 51.8 M ha of edge forests into interior forests. This enhanced carbon sequestration (1.4±0.2 Pg CO2e, a cooling biogeochemical effect), while reduced albedo (−0.9 Pg CO2e, a warming biophysical effect) partially offset the gain, yielding a net extra climate benefit of ...

Measuring rainfall to a forest canopy: an assessment of the performance of canopy level raingauges [PDF]

open access: yesHydrology and Earth System Sciences, 2004
Accurate rainfall measurements are crucial for water resource and environmental assessments but can be difficult to achieve in extensive areas of forest. This paper reviews the different techniques for measuring rainfall to a forest area and presents

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

open access: yesAdvanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.
