FLUX TOWER AT THE HUBBARD BROOK EXPERIMENTAL FOREST
We established the 31 m tall Rohn tower on a flat bench in the middle of the Hubbard Brook valley in August 2016. The forest around the tower is mixed hardwoods (sugar maple, American beech, yellow birch) with substantial hemlock patches. The approximate canopy height around the tower is 20 m.
The instrumentation on the tower includes:
- Gill sonic anemometer at 30 m
- LiCor 7200 open path H2O and CO2 analyzer at 30 m
- Kipp and Zonen net radiometer at 30 m
- Aspirated CS210 air T and relative humidity sensors at at 1.5 and 30 m
- Shielded air temperature sensors every 3 m from 3 m to 30 m
- Huske Flux heat conduction plates
- CS655 and Meter Teros21 soil sensors at 10, 20, 30, and 50 cm
Data for the tower are available through the Environmental Data Initiative and
AmeriFlux
repositories. Please use the data and if publishing with them, cite the data source. We are available to answer questions about the peculiarities of the site. In particular, Hubbard Brook is a mountainous valley and thus the terrain is not ideal for eddy covariance. Therefore, the calculated turbulent fluxes, particularly for CO2, should be carefully interpreted.
