The Development Of A New Anemometer For Measuring High Speed Winds On Mount Washington, New Hampshire, Mark W. Thoren
The Development Of A New Anemometer For Measuring High Speed Winds On Mount Washington, New Hampshire, Mark W. Thoren
Electronic Theses and Dissertations
Mount Washington, NH is well known as the "Home of the Worlds Worst Weather." Winds on the mountain regularly exceed 100 miles per hour, the record being 231 mph on April 12, 1934. There is a long history of weather observation on the mountain that has included various recording techniques. Until recently, the primary means of recording data has been paper strip charts. This project represents significant improvements to the Observatory's instrumentation system. Measuring windspeed on Mount Washington presents a number of design challenges. Any instruments directly exposed to the weather must be very durable. Fortunately this problem had been …

The current versus voltage (IN) characteristics of undoped and gold doped W03 thin film sensors were studied both experimentally and theoretically. A simplified equivalent circuit was formulated for the W03 sensor. It includes forward and reverse biased Schottky diodes which represent the contact region between the electrodes and the film and a resistor which represent the sum of crystallite resistance and the intercrystallite resistance between the individual crystallites. According to the electron transport mechanisms through the Metal Semiconductor (MIS) boundaries and intercrystallite boundaries, two kinds of yV and corresponding ResistanceNoltage(RN)characteristics are possible, one based on thermionic emission theory and the …
