Title: Climate and Terrestrial Microclimate Measurements at Mars Hill College, Buncombe County, North Carolina, 2004-2015
Abstract: This project contains data collected from three sites located on the campus of Mars Hill College in Mars Hill, NC. Microclimate data consisting of air temperature, relative humidity, and photosynthetically active solar radiation are collected at a central open site. Soil moisture, soil temperature, and air temperature data are collected at two forested locations: the Maintinance Facility and President's House sites. The 8 soil moisture sensors at each of these two sites are installed in NE, NW, SE, SW directions with a sensor installed approximately 20m and 40m from the center of the site in each direction. Data was collected every minute and then averaged hourly, and daily average values were also produced.
