Correction for ‘Updated and validated solar irradiance reference spectra for estimating environmental photodegradation rates’ by Jennifer N. Apell and Kristopher McNeill, Environ. Sci.: Processes Impacts, 2019, 21, 427–437.

Table 1 in the original article shows an incorrect value for the ozone parameter. Below is the correct version of Table 1.
Table 1 Chosen inputs for SMARTS used for comparison against data and calculation of reference spectra
Parameter Value
Site pressure Calculated based on latitude and altitude
Atmosphere Appropriate selection of reference atmosphere based on site latitude and season
Water vapor Variable (in cm, from AERONET data) or calculated from reference atmosphere
Ozone Variable (in DU, from remote sensing data) or 300 DU
Gaseous absorption Light pollution
Carbon dioxide 407 ppm
Extraterrestrial spectrum 1361 W m−2 Gueymard 2004
Aerosol model Shettle & Fenn rural model30
Turbidity Variable (from AERONET data) or 0.1
Albedo None

In addition, the citations for the use of the SMARTS model were incomplete. Ref. 1 and 2 listed below should have been included.

These changes do not affect the results, conclusions, or reference irradiance spectra that were published.


The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
