Meteorological Measurements 



Wind speed and direction, air temperature, humidity, and barometric pressure were 

 monitored at the Battelle site throughout the long-term data collection experiment. 

 Barometric pressure was also measured at the data trailer. 



The Battelle wind gauge was an R. M. Young Model 05 103-U swivel propeller gauge 

 mounted at an elevation of 10 m. The station is located approximately 200 m landward of 

 the shoreline. The intervening terrain contains three rows of sand dunes which reach a 

 maximum height of approximately 3 m. The Battelle meteorological station used a Vaisala 

 Model CS 105 gauge to measure barometric pressure and a Vaisala HMP 35 gauge to 

 measure air temperature and relative humidity. The data trailer barometric pressure gauge 

 was a Paros sensor of the same type used in the wave and water level gauges. 



The Battelle gauges for the wind, barometric pressure, relative humidity, and air 

 temperature were all sampled by the same method. One measurement for each parameter 

 was obtained every 10 sec. These measurements were then averaged over an hour (with all 

 data weighted equally), and this average hourly value was reported. Maximum wind gusts 

 were also reported as the maximum 1 0-sec sample in the hour. The wind direction was a 

 vector average of the direction the wind was coming from, measured clockwise from north. 

 Measurements made between 1:00 and 2:00 were reported as the 1:00 average. If a data 

 record had gaps, no average was reported for that hour. Gauges were calibrated yearly. 



Chapter 3 gives examples of these meteorological data and their availability are shown 

 in Table 5. In this table, "wind" refers to average speed and direction, and maximum gust 

 speed and direction; "temperature" refers to temperature and relative humidity.
