Title: Weather and Terrestrial Microclimate Measurements from sites located at Mars Hill University, 2004-2018
Abstract: This project contains data collected from sites located on the campus of Mars Hill University in Mars Hill, NC. Weather data includes measurements of air temperature, relative humidity, wind speed and direction, precipitation, and photosynthetically active solar radiation. Soil moisture, soil temperature, and air temperature data were measured at two forested locations. At each forested location, eight soil moisture sensors were installed in transects radiating NE, NW, SE, and SW from the datalogger. Sensors were installed approximately 20m and 40m along the transect. Measurements were taken every minute and hourly and daily data values recorded.
