Title: Continuously measured forest soil moisture at four sites in the Coweeta basin.
Abstract: Volumetric soil water content was measured at four locations in the Coweeta Basin across a range of elevations. At each location, soil water content was measured from 0 to 30 cm and from 30 to 60 cm. In addition, air temperature was measured at 100 cm height and soil temperature was measured at 5 and 20 cm depth. At two locations photosynthetic available radiation (PAR) was measured below and above canopy. Measurements are recorded every 60 seconds and data output hourly.
Key Words: air temperature, photosynthetically active radiation, soil moisture, soil temperature, soil water
LTER Core Area: Inorganic Fluxes
CWT Themes: Soil Moisture, Hydrology, Water Quality and Quantity
Study Type: Coweeta LTER Long Term Monitoring
Study Period: 01-Jan-2000 to 19-Feb-2015
