Abstract

An autonomous low-power device for the precise measurement (±0.7 mbar) of atmospheric pressure versus date/time in Arctic conditions (-55° C, 120-km/hr wind) is described. Data are stored using `burned in silicon´ technology. Measurements are made every hour on the hour over a period of 12 months. Static pressure is measured using a special port designed to be insensitive to the effects of wind. Endurance problems associated with a one-year instrument operating in extremely harsh conditions are discussed
