Title: Weather Data from the city of Robbinsville, Graham County, North Carolina.
Abstract: This data set contains measurements of air temperature, relative humidity, wind speed, wind direction, PAR density, and rainfall from a site located in the city of Robbinsville, Graham County, North Carolina. Air temperature, relative humidity, wind speed, and PAR density are measured every 60 seconds with average, minimum, maximum, and discrete top of the hour values saved to the output data table 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. Calculations for dew point, heat index, wind chill, and wind vector are calculated hourly and saved to the output data table.
