Description
The average station pressure during the last 5-minute interval.
- A short length of tubing extends from the pressure port to outside of the datalogger enclosure in order to expose the barometer to the free atmosphere.
- Barometric pressure is not corrected for the elevation of the station above sea level. However, changes in pressure over time at any given station are very accurate measurements.
Accuracy
± 0.4 mb for air temperatures between −30 and 50 °C
