The authors wish to make the following change to their published paper [1]. The following sentence on page 18
“The absorption coefficient (α) in turn is linked to the frequency (ω), particle concentration (c) and extinction coefficient (K), as illustrated in Equation (27) [79].”
is replaced by
“The absorption coefficient (α) in turn is linked to the frequency (ω), speed of light (c), and extinction coefficient (K), as illustrated in Equation (27) [79].”
The manuscript will be updated and the original will remain available. A link to this Erratum will be added.
