- eradiate.thermoprops.util.column_number_density(ds, species)[source]#
Computes the column number density of a given species in an atmospheric profile. The column number density is computed according to the formula:
\[N = \sum_{i=0}^{L-1} n_i \, (z_{i+1} - z_i)\]where
\(N\) denotes the column number density, \(z_i\) are the level altitudes and \(n_i\) are the number densities of that given species inside the \(L\) atmospheric layers.
