On May 13, two sapflow sensors were installed on each of 12 trees approx. 50 m SE of the turbulence tower. Heat flux data will be downloaded at approx. 2-week intervals, and anyone interested in the data should contact Jia Hu (jiahu@ucar.edu). At some point, heat fluxes will be converted to sapflow data and available to help constrain water flux measurements made at the turbulence tower. Sometime in the next couple of weeks, soil moisture sensors (3 depths) will also be installed at two locations within the sapflow array.
