Abstract: Microclimate data are collected at a central open site and soil moisture, soil temperature, and air temperature data are collected at the Facilities' Station and President's House sites. Data collected include reference temperature, air temperature, air humidity, solar radiation, soil moisture, and soil temperature. Data are collected each minute and averaged and output each hour. In addition, daily minimum, mean, and maximum values are output at the end of each day. Data at the two field study sites are collected across each plot with 8 soil moisture sensors, 2 soil temperature sensors, 1 air temperature sensor, and 1 reference temperature sensor.
Location(s), Described: Mars Hill College: 1) Microclimate Station 2) Facilities' Station 3) President's House
