central research plot (CP plots), and an average tree height of 9.9 m in the footprint of the eddy covariance measurements (SP plots), with the tallest trees reaching 41 m. The difference in tree height [...] profiles through the forest, tree physiological measurements of sap flow and stem diameter changes, eddy covariance flux measurements, continuous measurements of atmospheric NO, NO2 and O3 concentrations, and
must balance, as in a budget. We use tools such as stable isotopes, chambers, sap flux, and eddy covariance. Tree rings provide a means of looking backward in time, particularly with stable isotopic data

Time series of climate variables, ecosystem gas exchange (eddy covariance), tree physiology records (sap flow, stem radius changes), and air pollution data cover the history [...] Deflection and Calculating the Intercepted Snow Mass on Spruce Branches.
