This data set contains 15-min sapflux data from 12 aspens at the T.W. Daniels Experimental Forest in Logan Canyon, along with meteorological and soil temperature and moisture measurements. The sapflux data are presented as raw data as well as processed data. Filtering steps were done to remove bad data- the intermediate filtering steps are also included for clarity. Sapflux data collection commenced on 13 May 2014 and continued until 12 July 2015. A complete description of the methods can be found in: AM Chan, (2015), "Tree Transpiration from Two Forests in the Wasatch Mountains, Utah", MS Thesis, Dept of Biology, University of Utah.
