pvl_pres2alt

Determine altitude (m) from site pressure (Pa).

Contents

Syntax

altitude = pvl_pres2alt(pressure)

Description

altitide = pvl_pres2alt(pressure) determines the altitude (in meters above sea level) of a site on Earth's surface given its atmospheric pressure (in Pascals).

Assumptions

Outputs

Example

Alt1 = pvl_pres2alt(101325) % Sea level, result should be near zero
Alt2 = pvl_pres2alt(80000) % Approximate pressure near 2,000 meters abobe sea level
Alt1 =

    0.1243


Alt2 =

   1.9491e+03
