Washington, Puget Sound: Ferry Weather

Mobile weather stations have been installed on several ferries in the State of Washington ferry system. The stations measure meteorological parameters along their routes at locations in the Puget Sound where such data was previously unavailable. The weather stations were integrated into the already existing Ferry Tracking System and consist of a CR10X datalogger and temperature, barometric pressure, relative humidity, and wind speed and direction sensors. The movement of the ferries makes measuring wind speed and direction especially tricky. Accurate data is obtained by correcting the reading with the ferry's gyrocompass, a GPS, and an RF modem. The project was integrated by Meteor Communications Corp.
