In some locations, no nearby meteorological data are available to use in determining forcing terms and other analysis. In these cases we deploy either land- or buoy-based meteorological stations.
Onset HOBO Weather Station
The Onset weather station is a self-contained, battery-powered, weatherproof system for measuring and recording wind direction, speed, and gust; air temperature; pressure; relative humidity; short wave radiation; and photosynthetically active radiation. It is used mounted on a mast for land-based measurements (fig. 29) and employs a small solar panel to keep parts of the logger charged. We have used the default sensors, but other options may be installed if more accuracy is required. More information about the system and sensors is available at http://www.onsetcomp.com/products/data-loggers/weather-stations.
Down East Buoy-Mounted Weather Station
This automated weather station is designed be mounted in the hull of a surface buoy (fig. 30) and deployed as part of a surface mooring. It can withstand the rigors of the marine environment and acquires wind speed, direction, air temperature, pressure, and relative humidity data from its sensors at 15-minute intervals. The position is incorporated into the data stream, allowing buoy motion to be tracked. Because it has solar panels to charge the system, near real-time data telemetry to land is possible.
