Sensors Seven 2-D sonic anemometers were mounted on separate tripods at ground level around the Heber Wells Building. The sensors collected wind speed and direction data every second. Ten-minute averages and standard deviations were computed. All seven sonics were 2.5 meters above the ground. The one-second data are also presented in files of 10-minute averages. Locations The following table shows the positions of the seven sonic anemometers relative to the release point. Sonic x_meters y_meters 1 -14.0 6.7 2 2.8 6.7 3 33.0 75.4 4 35.9 36.8 5 -54.0 79.4 6 -54.5 26.8 9 38.7 -29.2 Excel workbooks The ten-minute data are presented in Excel workbooks. Each workbook contains at least 7 worksheets. Worksheet Description Meta Serial numbers of the sensors. 10min Table of the 10-min data. Column descriptions ae below. Battery Chart of battery voltages. WS Chart of the wind speeds. WD Chart of the wind direcitons. ST Chart of sigma theta, the standard deviation of the wind angle. SU Chart of sigma U, the standard deviation of the wind speed. Data Below is a section of the 10-minute data. The time is from the beginning of the 10-minute period. The column headings follow the chart names in the previous table. The number that is a part of the column heading refers to the sonic number.
