The atmosphere module contains methods to calculate relative and absolute airmass and to determine pressure from altitude or vice versa.

Functions

absoluteairmass(airmass_relative[, pressure]) Determine absolute (pressure corrected) airmass from relative
alt2pres(altitude) Determine site pressure from altitude.
first_solar_spectral_correction(pw, ...[, ...]) Spectral mismatch modifier based on precipitable water and absolute (pressure corrected) airmass.
gueymard94_pw(temp_air, relative_humidity) Calculates precipitable water (cm) from ambient air temperature (C) and relatively humidity (%) using an empirical model.
pres2alt(pressure) Determine altitude from site pressure.
relativeairmass(zenith[, model]) Gives the relative (not pressure-corrected) airmass.
