pvl_alt2pres

Determine site pressure from altitude

Contents

Syntax

pressure = pvl_alt2pres(altitude)

Description

Determines the atmospheric pressure (in Pascals) of a site on Earth's surface given its altitude (in meters above sea level). Output Press is given in Pascals. Press is of the same size as altitude.

Example

Press1 = pvl_alt2pres(0) %Pressure at mean sea level
Press2 = pvl_alt2pres(1000) % Pressure at 1,000 meters obove mean sea level
Press1 =

   1.0132e+05


Press2 =

   8.9875e+04
