Regional Soil Moisture, Soil Temperature, and Air Temperature Sites

Mars Hill University

These sites are located on the Mars Hill University campus located in Madison County, North Carolina.  These forested sites are located near the University's maintenance facility and the school's president house.  The station at each site has soil moisture and soil temperature probes located 20 meters and 40 meters along NE, NW, SE, SW axes radiating from the center of the site where the station equipment is located and air temperature is measured.  Soil moisture is measured from 0-30cm and soil temperature is measured at 5cm below mineral soil surface. Measurements are taken every 60 seconds with average, minimum, and maximum values saved hourly to the output table.

Great Smoky Mountains National Park

High elevation sites were established within the Great Smoky Mountains National Park near Clingmans Dome and Noland Divide. Soil moisture measurements are taken at depths of 0-30cm and 30-60cm below the mineral soil surface.  Soil temperature measurements are taken at the mineral soil surface and at 30cm below. Probe locations are appx. 25 meters above and below gradient of the center of the site where air temperature and relative humidity are measured appx. 1.5 meters above ground level. Measurements are taken every 60 seconds with average, minimum, and maximum values saved hourly to the output table.

Bent Creek Experimental Forest

Three sites were established in the US Forest Service's Bent Creek Experimental Forest located in Asheville, NC.  The sites are located at ridge, side-slope, and cove areas in the Long Branch drainage.  Soil moisture probes are installed at depths of 0-30cm and 30-60cm below mineral soil surface at locations 6 meters from the plot center.  Soil temperature probes are located near the plot center and installed at 5cm and 20cm below mineral soil surface.  Air temperature measurements are taken near the plot center, appx. 1-1.7 meters above ground.  All measurements are taken and recorded at 5 minute intervals.

Beetree Reservoir Watershed

Three sites were established above the Beetree Reservoir near Swannanoa, NC.  The sites are located within an 8900 hectare forested and protected watershed that is the drinking water supply for the City of Asheville, North Carolina. The sites are located at ridge, side slope, and cove areas of a drainage basin for Beetree Creek. Soil moisture probes are installed at depths of 0-30cm and 30-60cm below mineral soil surface at locations 6 meters from the plot center.  Soil temperature probes are located near the plot center and installed at 5cm and 20cm below mineral soil surface.  Air temperature measurements are taken near the plot center, appx. 1-1.7 meters above ground.  All measurements are taken and recorded at 5 minute intervals.
