The dataset records the observed evapotranspiration time series from the green roof of the Marriott Library on the University of Utah's campus for the year 2014. Three weighing lysimeters were set up to represent three types of the surface cover including non-vegetated medium, sedum, and bluegrass. Daily values (mm/day) were recorded. The data collection was primarily funded by the Sustainable Campus Initiative Fund from the Office of Sustainability at the University of Utah, the Graduate Student Research Funding from the Global Change and Sustainability Center at the University of Utah, and iUTAH.

Data Processing Method Evapotranspiration rate was estimated as the sum of weight changes during the dry periods through a day.
