The above abstract is the abstract as it was submitted. Applied Optics says it too long: it should be no more than 100 words. For that reason the abstract has been shorted, though that makes the abstract sadly rather incomplete and not so well readable as the original abstract. The shortened abstract reads as follows.
The nadir-viewing Global Ozone Monitoring Experiment (GOME) spectrometer aboard the second European Remote Sensing satellite (ERS-2) measures spectra in the range 240-790 nm. For the near-real time delivery of ozone columns and profiles at KNMI, a wavelength calibration method was developed which allows for a variation in both location and width of the spectral bins along the detector. The resulting wavelength grid of earthshine spectra varies along an orbit. This variation shows a correlation with instrument temperatures for a window around 306 nm; for other wavelength windows there is no correlation. The wavelength grid of calibrated solar spectra shows fluctuations without an apparent pattern and no correlation with instrument degradation.
