- pyarts.plots.arts_lookup.calc_opacity_from_lookup(lookup, z=None, g=9.80665, r=287.0570048852906, tpert=0)[source]
Calculate the opacity from an ARTS lookup table.
- Parameters:
lookup (pyarts.arts.GasAbsLookup) – ARTS lookup table.
z (ndarray, optional) – Altitude profile. If not given, the layer thicknesses are calculated based on the hypsometric formula.
g (float, optional) – Gravity constant. Default uses Earth’s gravity.
r (float, optional) – Gas constant for dry air. Default uses constant for Earth.
tpert (int, optional) – Index of temperature perturbation to plot.
- Returns:
Opacity per species in lookup table.
- Return type:
ndarray
