Journal ArticleDOI
Wind loading of trees: influence of tree size and competition
TL;DR: In this paper, a linear relationship between the maximum hourly turning moment and the square of the average hourly wind speed at the canopy top was defined as the turning moment coefficient (T676 C).
Journal ArticleDOI
Measurement of the 13C isotopic signature of methane emissions from northern European wetlands

TL;DR: In this paper, isotopic signatures of emissions in the Fennoscandian Arctic have been determined in chambers over wetland, in the air 0.3 to 3'm above the wetland surface and by aircraft sampling from 100'm up to the stratosphere.
Journal ArticleDOI
Finite element analysis of trees in the wind based on terrestrial laser scanning data
Toby Jackson,Alexander Shenkin,Axel Wellpott,Kim Calders,Niall Origo,Niall Origo,Mathias Disney,Andrew Burt,Pasi Raumonen,Barry Gardiner,Martin Herold,Thierry Fourcaud,Yadvinder Malhi +12 more
TL;DR: In this article, the authors presented a new approach in the study of wind damage: combining terrestrial laser scanning (TLS) data and finite element analysis, which is applicable at the plot level and could also be applied to open-grown trees, such as in cities or parks.
Journal ArticleDOI

TL;DR: In this paper, the authors used tree motion time-series data to systematically evaluate the factors influencing tree responses to wind loading, including data from both broadleaf and coniferous trees in forests and open environments.
