Hill Demonstration Forest climate, soil moisture and tree water use data
This data publication contains daily vapor pressure deficit, solar radiation, soil moisture, sap flux density, tree transpiration, and precipitation data measured from 2018 to 2019 (pre-thinning) and 2020 (post-thinning) on a watershed planted with loblolly pines (Pinus taeda L.) in January 2012. The study site is on the Hill Demonstration Forest (owned and managed by North Carolina University) and is located north of Durham, North Carolina. Sap flux density and tree transpiration were measured from both loblolly pine and shortleaf pine (Pinus echinata Mill.). Sap flux density is a localized measure of water movement through the tree at a specific point. Transpiration is computed from sap flux density however it is a whole-tree process, representing the total water used and released by the tree.
Hill Demonstration Forest and Umstead Research Farm climate data
This data publication contains hourly climate data from a weather station that was located in an open area on the Hill Demonstration Forest (HF) from 2007 to 2020. The HF is located north of Durham, North Carolina and owned by North Carolina State University. Given the proximate location of HF to Umstead Research Farm (UF) (5 miles), the climate data from HF can be used to represent the climate conditions at UF (due to limited funds, there was no weather station installed at UF). UF is located north of Durham, North Carolina and is owned by North Carolina Department of Agriculture & Consumer Services. Measurements include air temperature, relative humidity, dew point, solar radiation, vapour pressure as well as wind speed, gust and direction.
Hill Demonstration Forest HF1 riparian buffer climate data
This data publication contains hourly climate data from a weather station that was located in the riparian buffer in a watershed (HF1) on the Hill Demonstration Forest (HF) (2010 – 2016). The HF is located north of Durham, North Carolina and owned by North Carolina State University. Measurements include air temperature, shortwave, longwave, and net radiation, relative humidity, wind speed, and wind direction.
Hill Demonstration Forest HF1 and HF2 riparian buffer and HF2 upland sap flow data
This data publication contains hourly sap flux data from three locations (defined as HF1 riparian buffer, HF2 riparian buffer, and HF2 upland) in a pair of watersheds on the Hill Demonstration Forest (HF). Sap flux density was monitored at the HF1 riparian buffer location in the following species from 2010-2016: loblolly pine (Pinus taeda), sweetgum (Liquidambar styraciflua), red maple (Acer rubrum), white oak (Quercus alba), and tulip poplar (Liriodendron tulipifera). At the HF2 riparian buffer location sap flux density was monitored from 2010-2016 in the following species: loblolly pine, sweetgum, red maple, tulip poplar, American beech (Fagus grandifolia), white oak, and Virginia pine (Pinus Virginia). Thirdly, sap flux density was monitored at the HF2 upland location from 2015-2016 for the following species: loblolly pine, sweetgum, red maple, tulip poplar, chestnut oak (Quercus montana), and Virginia pine.
Hill Demonstration Forest HF1 and HF2 riparian buffer and HF2 upland soil moisture data
This data publication contains hourly soil moisture data from three locations (defined as HF1 riparian buffer, HF2 riparian buffer, and HF2 upland) in a pair of watersheds on Hill Demonstration Forest (HF). Hourly soil moisture readings were monitored from 2010-2016 at the HF1 and HF2 riparian buffer locations at depths of 10 centimeters (cm) and 30 cm. At the HF2 upland location hourly soil moisture readings were monitored from 2015-2016 at depths of 10 cm and 60 cm.
Hill Demonstration Forest and Umstead Research Farm precipitation data
This data publication contains hourly precipitation readings collected from a tipping bucket on the Hill Demonstration Forest (HF) and Umstead Research Farm (UF) from 2007 to 2020. Both sites are located north of Durham, North Carolina. The HF is owned by North Carolina State University and UF is owned by North Carolina Department of Agriculture and Consumer Services.
Hill Demonstration Forest and Umstead Research Farm streamflow data
This data publication contains hourly streamflow readings from three pairs of watersheds on the Hill Demonstration Forest (HF) and Umstead Research Farm (UF) from 2007 to 2013. Both sites are located north of Durham, North Carolina. The Hill Forest is owned by North Carolina State University and Umstead Research Farm is owned by North Carolina Department of Agriculture and Consumer Services.
