pvlib.atmosphere.get_absolute_airmass(airmass_relative, pressure=101325.0)[source]#

Determine absolute (pressure-adjusted) airmass from relative airmass and pressure.

The calculation for absolute airmass (\(AM_a\)) is

\[AM_a = AM_r \frac{P}{101325}\]

where \(AM_r\) is relative air mass at sea level and \(P\) is atmospheric pressure.

Parameters:
  • airmass_relative (numeric) – The airmass at sea level. [unitless]

  • pressure (numeric, default 101325) – Atmospheric pressure. [Pa]

Returns:

airmass_absolute (numeric) – Absolute (pressure-adjusted) airmass
