pressure = antatm(elevation)
This function converts elevation in meters to atmospheric pressure in hPa using the pressure-elevation relationship:
The pressure-elevation relationship is derived from:
Radok, U., Allison, I., and Wendler, G., 1996. Atmospheric pressure over the interior of Antarctica. Antarctic Science 8, pp. 209-217.
