Title: Continuously measured soil moisture, soil temperature, and air temperature from stations in Watershed 36, Coweeta Hydrologic Laboratory
Abstract: Long-term soil moisture stations were established within the Coweeta Hydrologic Lab Basin to collect measurements of soil moisture, soil temperature, air temperature, and relative humidity at a range of spatial scales, from ridge to cove and low to high elevations in the southern Appalachians, and across the regional range of rainfall amounts.
Key Words: air temperature, Coweeta Hydrologic Laboratory, elevation gradients, hydrology, microclimate, soil moisture, soil temperature, soil water content, southern Appalachian Mountains, time domain reflectometry, water availability
