Title: Weather measurements above the Cullasaja River, Highlands, NC
Abstract: This data set contains measurements of air temperature, relative humidity, wind speed, wind direction, solar radiation, and rainfall from a site located above the Cullasaja River near Highlands, North Carolina. Air temperature, relative humidity, wind speed, and solar radiation are measured every 60 seconds with average, minimum, maximum, and discrete top of the hour values saved to the output data hourly. Wind direction is measured every 60 seconds with the average value saved to the output data table every hour. Hourly rainfall is totalized and a continuous 24 hour rainfall value is calculated. Evapotranspiration is also calculated.
