Walker Branch Watershed: Daily Climate and Soil Temperature Data

This data set reports daily climate and soil temperature data for Walker Branch Watershed. As part of the long-term Walker Branch project, daily climate and soil temperature data were collected using instruments on a meteorological tower located in an upper slope of the watershed. This data set contains one data file of daily climate and soil temperature data from 1993 through 2010. Measurement collection began in 1993 as part of the Throughfall Displacement Experiment (TDE) in the control (ambient) plot. Measurements include daily integrated values for above canopy incident photosynthetically active radiation, above canopy incident total radiation, air temperature, relative humidity, rainfall, soil temperature at 10-15 cm, and wind speed. Measurements of incoming rainfall, irradiance, and photosynthetic photon flux density were obtained in a nearby clearing until 1998 when above canopy observations were added to the ambient plot tower. The Walker Branch Watershed is located on the U.S. Department of Energy’s Oak Ridge Reservation in eastern Tennessee.
