Working with Niles, Natalia, Jose, and Kersti, we have measured sapflux and the stable isotope composition of phloem sap around the tall tower at Svartberget. We will use these data to estimate GPP and compare these estimates to those from eddy flux and from Kersti's model. For precise work, this method requires knowledge of the isotopic composition of CO2 in the tree canopy. We aim to set up this measurement on the tall tower by attaching a Picarro CO2 isotope analyzer to the tower inlets.
