6. PRESSURE
Atmospheric Pressure values (in hPa) are given after reduction in the mean sea level (no temperature corrections are applied).
Furthermore, the short-term pressure variability (in respect to the mean-value of the past 10 minutes) is marked by an arrow "↑" for an increasing trend and by a "↓" for a decreasing trend.
Air Pressure measurements are made by the Vaisala PTB110 Barometer[†]
[†] Range : 600 ~ 1100 hPa - Resolution : 0.1 hPa - Accuracy : ± 0.3 hPa
