KLUMI (47.59359 N , 54.27349 W) is a 10 m mast weather station equipped with a Gill ultrasonic wind sensor (WindSonic, option 4). The data are collected via a SUTRON Satlink2-V2 logger connected to an Omni-directional GOES antenna; transmitting near real-time data every hour. 1 min average wind speed and direction as well as gust (maximum) are calculated from the sensor 1 Hz internal sampling rate and recorded by the logger every 10 min. The mast is installed on a barren island, about 10 m height from the mean sea level, located on the northeast side of Placentia Bay. Wind observations are thus made at about 20 m from mean sea level. This weather station is part of a monitoring program led by the Northwest Atlantic Fisheries Centre (Fisheries and Oceans, Canada) to provide with an oceanographic baseline of the area.
