On 17 March 1999 I started on a post-doc. job for a period of five years at the Royal Netherlands Meteorological Institute (KNMI), in the research division then called Atmospheric Composition, later names Climate Observations.
This new wavelength calibration has been converted, together with some other corrections, into a software package called GomeCal. Other users of GOME data can use the package to re-calibrate the measured spectra. The package was released in 2003 via the GomeCal home page at the GOME Fast Delivery website of KNMI, which is no longer available, since updates of the GOME spectral data have made this package obsolute.
Additionally, I took part in retrieving an Aerosol Absorption Index (AAI) based on GOME measurements and briefly tried my luck on retrieving concentrations of sulphur dioxide (SO2), which comes into the atmosphere e.g. due to antropogenic polution and volcano eruptions, as a test of the method developed by others.
The work was first part of a project called GOFAP.
That project was set up to create a GOME Fast Delivery Service [the website of which has been deleted around 2010], to provide ozone columns, ozone profiles and assimilated global ozone maps from GOME data on a near-real time bases, i.e. within 3 hours after the measurement (the nominal delivery of total ozone columns from GOME is between two weeks and two months after acquisition).
The results of such fast delivery services can be used for improving numerical weather prediction models, radiation and UV forecasts and ozone measurement experiments.
Some additional information on ozone:
===> The 1999 ozone hole as seen by GOME (110 kb)
(there will be no such page on the ozone hole of other years)
===> About ozone and the formation of the ozone hole
===> list of my publications about my post-doc. positions in atmospheric research.

for the meaning of some acronyms.
