This is a complete data set that includes sapflux data from 12 aspens and 12 white firs at Knowlton Fork in Red Butte Canyon. Raw 15-min sapflux data for each tree along with processed data are included as well as met data for the site. 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 began on 23 August 2013 and continued until 5 December 2013 and was then re-started on 20 February 2014 and continued until 5 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.
