The Measurement campaign at Järvselja Experimental Forestry Station takes place in the time from 04. - 17. August 2008.
Short site description:
The Järvselja Experimental Forerstry Station is located approx. 50 km SEE (by crowfly) out of the city of Tartu. The terrain is flat and the measurement site is located at the western border of the area belonging to the Station. The current place where the towers are located is a mixed birch and spruce stand (approx. 16-18, canopy height) with some lime trees and poplars within. Tower height is 20 m.

Under and overstorey systems are already set up.
Understorey: CO2, H2O, Temperature, Humidity
Overstorey: CO2, H2O, Temperature, Humidity, Isoprene

First steps to sample VOC with the Walz Cuevette system measureing understorey birch leaves. PhD student Leila Pazouki follows the photosynthesis measurements. VOC sampling was done by usage of the sample outlet, CarboPack Cartridges and contrloling the outlet flow via a digital flow meter. (© 2008 Steffen M. Noe)
CO2, H2O, Methane, NOx

A measurement cottage has been raised, electricity (230V~, 6A) is provided with two phases and additionally a generator (230V~, 6A) can be used.
