Can increased training and awareness take forest research to new heights?
Trees, Forests and People, 2020 Forest canopies contribute significantly to global forest biodiversity and ecosystem functioning, yet are declining and understudied. One reason for a knowledge gap is that accessing forest canopies can be difficult and dangerous.

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

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