Abstract

A new method for correcting the wavelength misalignment in measured UV spectra is presented. It is based on a comparison between measured irradiances and irradiances computed from a radiative transfer code for a set of given atmospheric and solar conditions (250 < Dobson units < 450, 30° < solar zenith angle < 75°). Results of tests run with spectra recorded on a clear-sky day by two spectroradiometers in a French UV spectral network station are analyzed. Applying the method once reduces shift to less than 0.05 nm. The smoothing included in the method enables detection of aberrant irradiance values and then completion of an initial quality control of measured spectra. A technique for assessing the instruments’ slit function is also presented. The key algorithms needed to build a computer code based on this method are given.

Wavelength misalignment of solar global spectra from two spectroradiometers. The spectra used were recorded on 18 September 2000 at 11:00 UTC in the French Alps. Misalignments before correction are represented by the thin curves; those taken after correction are shown as bold curves. (a) and (b) present misalignments computed with our new method; (c) and (d) present those computed with the SHICrivm algorithm, version 2.7.

Fig. 4

Normalized spectra of the ratios’ shift-corrected measured and computed irradiance for FWHM values from (a) IRSA-UV data and (b) SPUV-02 data. The shift-corrected irradiances are global values recorded at 11:00 UTC on 18 September 2000 in the French Alps. The spectra are at 0.1 intervals along the y axis; the gap between two minor ticks is 0.02.
