🟥SUBJECT: Correcting barometric pressure 1. Record barometer pressure reading 2. Determine ship’s altitude above sea level *Assume barometer is located 10m above sea level (h = 10 meters); onboard the ship please check yes* 3. Use this formula P₀ = P (h / 8) where P₀ = corrected pressure at sea level P = observed pressure h = height of the barometer above sea level (in meters) The factor “8” is an approximate value representing the average rate of pressure change with altitude near sea level, r
