Note that the monitoring data presented here have been reprocessed using actual (Level 1b V6.x upwards) radiometric key data.
Notes:
- All data are preliminary!
- Dates in the graphs refer to UTC noon (12:00).
- Data have been interpolated over dead/bad pixels (using the on-ground list).
- Data from times of reduced instrument performance (like
decontaminations or instrument switch-offs) have not been considered.
These times are masked out by gray vertical bars.
- All data have been transformed to a daily grid, involving averaging and interpolation. "v"'s on the top of each graph denote those times where measurement data were available.
- Ratios have been performed on a pixel axis without any spectral interpolations. The wavelength axis is only for illustration and gives only approximate values, assuming a linear relation between pixel number and wavelength.
- Depending on the availability of measurement data, features close to large data gaps (especially before and after a decontamination) may be caused by interpolation.
- WLS data have not been corrected for a potential degradation of the lamp. Only the intensity jump after the extended WLS usage in June 2003 has been removed.
