Barometric pressure

Barometric pressure is available as one- and thirty-minute averages for station pressure, which is determined from 0.1 Hz observations. Barometric pressure corrected to sea level and surface level (defined as water surface at aquatic sites and soil surface at terrestrial sites) is derived from station pressure averages and available at one- and thirty-minute increments. Observations are made by a single digital barometer located on the tower infrastructure and a single digital barometer located on the aquatic meteorological station.
