- 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
