With its 25 meters, the new scaffolding tower is replacing the old mast, which had become overgrown by forest. The new tower will be much easier to access for future maintenance. Alongside the tower, both the sensors and the logger-system have been updated.
Initially, the tower will support measurements for the SITES Spectral Thematic Program using light sensors and multi spectral camera. However, there are plans to potentially install flux measurement sensors in the future.
The tower is located in a Norway spruce stand planted after the storm of 2005. It is part of the Asa High-yield Experimental Forest. which is fertilized every second year. Despite being only 20 years old, the stand has already reached an average height of around 10 meters and an average diameter of 10.7 cm. The current standing volume is approximately 105 m³/ha.
