GetSeaLevelPressure {psychrolib}

Return sea level pressure given dry-bulb temperature, altitude above sea level and pressure.

Description

Return sea level pressure given dry-bulb temperature, altitude above sea level and pressure.

Usage

GetSeaLevelPressure(StationPressure, Altitude, TDryBulb)

Arguments

StationPressure

A numeric vector of observed station pressure in Psi [IP] or Pa [SI]

Altitude

A numeric vector of altitude in ft [IP] or m [SI]

TDryBulb

A numeric vector of dry-bulb temperature in degreeF [IP] or degreeC [SI]

Value

A numeric vector of sea level barometric pressure in Psi [IP] or Pa [SI]

Note

The standard procedure for the US is to use for TDryBulb the average of the current station temperature and the station temperature from 12 hours ago.
