eradiate.thermoprops.util.column_mass_density(ds, species)[source]#

Computes the column (mass) density of a given species in an atmospheric profile. The column mass density is computed according to the formula:

\[\sigma = N * m_u\]

where

\(\sigma\) denotes the column mass density, \(N\) is the column number density, \(m_u\) is the atomic mass constant.

Parameters
  • ds (Dataset) – Atmosphere thermophysical property data set.

  • species (str) – Species.

Returns

quantity – Column mass density.
