Simultaneous measurement of tree movement and wind flow is essential for understanding the complex interaction of tree motion and wind within and above canopies. It is, example, required to improve our understanding of the turbulence structure above and within canopies and the resulting influence of the turbulence on momentum exchange and gas fluxes. It is also vital in understanding the process of wind damage to individual trees and forests, and for testing models predicting the risk of wind damage.

In the past few decades there have been rapid developments in the methodologies to determine tree motion.  At the same time wind measurements have progressed from cup anemometers and sonic anemometers to wind LiDAR systems that can scan a 3-dimensional space. All the measurements have individual strengths and weaknesses and all need to be properly utilised and the data correctly analysed. This requires a full understanding of how the instruments work, what are their weaknesses and known limitations, and how the output signals/information are created and stored.

The purpose of the workshop

In this workshop you will:

  • Compare techniques and learn good practice in the measurement of tree movement and wind loading, and in the measurement of the wind in and above forests.
  • Be informed of the correct tree movement or wind measurement system to use in specific circumstances and for specific user requirements.
  • Learn how to calibrate instruments, the specific issues and difficulties with each instrument, and how to collect, filter and analyse data correctly.

The event is organised by Ebba Dellwik (Danish Technical University), Barry Gardiner (EFI/Forest Research) and Tom Locatelli (Forest Research).

You can find more information and reserve a place on the event's web page.

The event costs 190 Euros and the deadline for registration is 8th April 2018.  Spaces are limited to only 30 participants!

The cost of the workshop includes lunch and refreshments during the 3 days workshop.

Please bring clothes for varied weather.

If you have a specific instrument that you are able to bring, please contact the organizers who will investigate whether it can be installed given the local infrastructure no later than March 16th. You are also very welcome to bring your own data.
