pvlib.atmosphere.pres2alt(pressure)

Determine altitude from site pressure.

Parameters:pressure (numeric) – Atmospheric pressure. [Pa] Returns:altitude (numeric) – Altitude above sea level. [m]

Notes

The following assumptions are made

Parameter	Value
Base pressure	101325 Pa
Temperature at zero altitude	288.15 K
Gravitational acceleration	9.80665 m/s^2
Lapse rate	-6.5E-3 K/m
Gas constant for air	287.053 J/(kg K)
Relative Humidity	0%
