A meteorological station was deployed on the dam to measure hourly relative humidity, wind speed and direction, and photosynthetically active radiation between August 3, 2012 and October 30, 2014, with air temperature and solar radiation added on April 30, 2013. Additional meteorological data were obtained from the National Climatic Data Center (2015): Precipitation data were obtained from Pierce, Nebr.; Air temperature, wind speed, and wind direction data were obtained from Norfolk, Nebr., and were used to fill gaps in measured meteorological datasets. These gaps primarily corresponded to the period between the beginning of the furnished data (January 1, 2012) and the onset of measurements on the dam (August 3, 2012 or April 30, 2013 depending on the measurement).
