CCI+P Glyoxal tropospheric column L2 data from GOME-2B

Glyoxal (CHOCHO) tropospheric vertical columns retrieved from GOME-2/MetOp-B observations as part of the ESA CCI precursors for aerosols and ozone project.

This dataset provides a set of L2 glyoxal vertical columns obtained from GOME-2/MetOp-B, for the period of January 2013 until December 2023. The retrieval is based on the TROPOMI glyoxal retrieval method developed for the GLYRETRO and S5P-PAL projects, but features more precise air mass factor calculations using a directional surface albedo database based on GOME-2 observations, and a set of daily a priori glyoxal profile shapes obtained using the MAGRITTE chemical transport model.
